A critical security flaw in Issabel Framework, a web-based framework for the open-source unified communications PBX software, has come under active exploitation. The vulnerability in question is CVE-2026-89026 (CVSS v3.1 score: 9.8/CVSS v4.0 score: 9.3), which can allow an unauthenticated remote attacker to execute arbitrary operating system (OS) commands by taking advantage of a hard-coded

Overview A vulnerability exists in Sentry Seer when the system is configured to automatically hand issues to a coding agent for remediation. Successful exploitation results in arbitrary code execution within the coding‑agent environment and access to connected source repositories. This vulnerability is tracked as CVE-2026-90999 . Description Sentry is a software error‑monitoring and performance‑tracking platform used by developers to detect, diagnose, and understand issues in their applications. It collects telemetry such as exceptions, stack traces, logs, and performance data from applications. Built into Sentry, Seer acts as an automated debugging assistant that converts telemetry into actionable remediation steps and can hand off issues to an integrated coding agent to propose code fixes. Because Sentry front-end projects commonly expose a public DSN (Data Source Name) to allow browsers to submit this telemetry, an attacker can craft and submit malicious events through this public endpoint. When Seer is enabled to automatically pass issues to a coding agent, these attacker-supplied events can traverse multiple trust boundaries. Ultimately, malicious event fields propagate through Seer’s analysis pipeline, transforming into untrusted instructions that the privileged coding agent may execute. The vulnerable workflow is as follows: * Sentry ingests attacker‑generated exception events submitted through the public DSN. * Seer evaluates whether the event represents an issue eligible for automated remediation. * Seer generates a root‑cause analysis that uses attacker-controlled event fields, including exception messages, stack traces, source context, and breadcrumbs. * The generated analysis is embedded directly into the initial prompt provided to the coding agent.

Most of the world’s governments tell you that you need to be post-quantum prepared by 2030-2035. For example, the US government says critical infrastructure should be key-exchange-prepared by the end of 2030 and authentication-prepared by the end of 2031 (ignore for now that they have the threats exactly backward). Non-critical infrastructure has until the end of 2035. There are a few governments saying critical infrastructure should be prepared by 2029, and many large tech companies, such as Google, Cloudflare, and Microsoft, say they plan to be prepared by 2029. But what happens if Q-Day happens in 2028? I cover this topic in my latest post-quantum books, *Becoming Post-Quantum: Your Guide to Post-Quantum Success* ([https://www.amazon.com/dp/B0HHTBDZ7T](https://www.amazon.com/dp/B0HHTBDZ7T)) and *Becoming Post-Quantum: Your Post-Quantum Project Plan* (Companion Book) ([https://www.amazon.com/dp/B0HJJJ675G](https://www.amazon.com/dp/B0HJJJ675G)). This isn’t a rhetorical question. IonQ has recently stated (https://www.ionq.com/news/ionq-publishes-worlds-first-fully-compiled-end-to-end-blueprint-for-breaking-256-bit-elliptic-curve-signatures) that it is realistic that its quantum computers could break traditional asymmetric cryptography used by everyone by 2028. To be clear, a paper is not a working cryptographically-relevant quantum computer. But it is a clear sign that IonQ thinks that it is not out of the realm of possibility. I wrote about this last week: [https://www.linkedin.com/pulse/should-you-post-quantum-prepared-2028-roger-grimes-vo9le](https://www.linkedin.com/pulse/should-you-post-quantum-prepared-2028-roger-grimes-vo9le). Note: It takes a lot more than just stable, logical working qubits to make a cryptographically-relevant quantum computer. Marin Ivezic’s analysis is the best I’ve seen on the subject: [https://postquantum.com/crqc-capability-framework/](https://postquantum.com/crqc-capability-framework/). But getting lots of stable, usable error-corrected qubits is one of the biggest challenges, if not the most challenging part. Most organizations haven’t even started an official post-quantum project yet. They are late. They need to start now! ASAP!! But even if your organization has started an official post-quantum project, it’s likely that the estimated “Q-Day” (i.e., the day when the first quantum computer breaks traditional asymmetric encryption) that the entire project is running on is probably 2030-2035. What happens if Q-Day happens in 2028 or 2029? Well, you’ve got to accelerate your post-quantum project, of course. All of it. It would be a massive immediate refocusing of resources. It would likely result in your organization being less efficient and productive (unless you are a vendor in the post-quantum space). You would have to reach out to your immediate boss, executive management, and the board of directors, if you have one, and tell them what just happened. Then you would gather all the necessary resources for an emergency meeting. You would immediately start your cryptographic inventory. Instead of having a year plus to conduct it on all critical systems, you would start conducting it focused first and best on your top critical systems. Ultimately, you would want your cryptographic inventory finished as fast as possible (e.g., a week, a month, a quarter) on your most critical assets. You would then make emergency decisions regarding what can be reconfigured, what needs to be upgraded, what needs to be replaced, what needs to be decommissioned, and what needs to be physically isolated. You would be making these decisions quickly. You might need to hire extra resources well beyond what you have today to conduct the post-quantum project superfast. Do you have those post-quantum vendors selected today? Do you know any? If not, start figuring out whom to call when. What cryptographic inventory software will you use? None are perfect. None inventory everything. But you need to use one (or more) to help you collect your cryptographic inventory as quickly as you can. You should do your research and make these two selections now, so you'll have them when you need them. \[Hint: You need them now, regardless of Q-Day dates.\] On a practical note, if your adversaries can use quantum computers against you (you’d have to calculate the risk of them actually doing so), you would need to implement monitoring tools, processes, and policies to be able to detect a quantum compromise. Is there a way to detect a successful quantum attack? For key exchange breaks, probably not. Other than you learn that previously protected information seems to be known by unauthorized entities. For authentication breaks, you would look out for fake digital certificates and use, and other related artifacts, such as fraudulent successful logons, fraudulent websites with fraudulent “valid” digital certificates. You would need to threat model the various quantum threats against your environment and then create and implement the appropriate protective and detective controls.   You would need to update your SOC (if you have one) and potentially your incident response policies and procedures. How do you respond to a quantum attack if you actually detect one? How do you respond to stolen data? How do you respond to a fraudulently used “valid” digital certificate and its use? In the latter case, you would certainly get the fraudulently used digital certificate revoked, warn stakeholders of the use, and get other related fraudulent assets removed and/or taken down. Ultimately, you need to threat model the various quantum attacks that would be possible against your company and take the appropriate preventative, detective, and incident response controls, like you would against any threat. Only this threat is quantum and new. I would also recommend that you focus on mitigating authentication threats first ([https://www.linkedin.com/pulse/us-government-gets-pqc-threats-exactly-backward-you-should-grimes-sx7ee](https://www.linkedin.com/pulse/us-government-gets-pqc-threats-exactly-backward-you-should-grimes-sx7ee)) over key exchange threats, if you can’t do them both at the same time. This goes counter to every other post-quantum expert telling you what to do first. I’m right. They are wrong. Regardless of whether Q-Day comes early or not, it’s cheaper and better to do it sooner than later. I wrote about that here: [https://www.linkedin.com/pulse/why-become-post-quantum-now-versus-later-roger-grimes-wiboe](https://www.linkedin.com/pulse/why-become-post-quantum-now-versus-later-roger-grimes-wiboe). With this post, I just want you to consider what you and the world are going to look like if Q-Day happens years earlier than most governments are telling you to be prepared for. There is at least one quantum computer vendor that is saying it’s not insane to think it might happen in 2028 or soon thereafter. The possibility is non-zero. You need to make that part of your post-quantum plans. It would be irresponsible not to.

As more teams — and now agents — build applications on Cloudflare's Developer Platform, having the right access controls is crucial to allow you to ship safely. After all, the last thing you want is for an agent to make a change in production, just because it was granted more access than it needs. Now, you can give a teammate or agent access to a specific Worker, so that they can only make changes to that application and no other resources in your account. Moreover, we’re giving you four new roles, so you can limit exactly what they can do: The new roles are available today, for all customers. You can assign them to a specific user, so when they log into the dashboard, they will only see the Worker you have given them access to. Or, you can create an API token with the scoped access, which you can give to your agent to ensure they only have access to that one application. Here’s an example of how to create an API token with permissions per Worker: Roles designed for how teams build When defining these roles, we wanted to strike the right balance. Overly broad roles force you to grant more access than intended, undermining the principle of least privilege, while providing too many individual permissions makes it difficult to know which ones to grant. We landed on four roles that reflect the levels of access you may want to give a person or agent: enough to debug a resource without exposing its content, read the content without changing it, make changes without being able to delete the resource, or fully manage it. We plan to use these same roles as we bring resource-level access controls to other Developer Platform products, including D1, R2, and KV. Each role can be applied at one of three scopes. For example, if you set the “metadata read-only” control, here’s what that would look like at different levels: Developer Platform level: Access

Without proper controls, website owners have long faced a difficult tradeoff: allow your content to be used for AI training, or risk losing discoverability in search. That tradeoff exists because some of the largest organizations on the Internet use mixed-use crawlers: a single crawler serving both search and AI training. Refuse one, and you refuse the other. Today, Cloudflare is announcing a new Disallow AI Training setting that lets you easily stay indexed for search while refusing to let that same crawler train on your content. Apple, Google, and Microsoft honor or have committed (in a specified time frame) to honor this setting. Mixed-use crawlers were the hard part of the training question. AI Summaries are next. A site-wide yes or no is too blunt: how much of your content appears in a summary matters as much as whether it appears at all. An opt-out for AI summaries is already one of the requirements we've set for mixed-use crawler operators. By early next year, our goal is to let you control how much of your content is included — set once on Cloudflare, rather than with each operator separately. Why asking isn’t enough Most site owners want to be found: by humans, agents, and (good) bots. But a significant portion of the open Internet is funded by advertising, subscriptions, or direct relationships with visitors, and those models only pay when someone actually arrives. Almost every site owner considers Search beneficial: less than 1% of Cloudflare sites choose to block Search bots. Training, however, is a different story: 17% of sites choose to enable some mechanism to block training. This is exactly why we decided site owners needed more granular controls, rather than a one-size-fits-all “Block AI.” A robots.txt directive alone cannot solve this problem. Anyone can publish one, but it cannot identify who i

Overview An out-of-bounds (OOB) memory access vulnerability involving unchecked array indexing has been identified in the exllamav3_ext compute unified device architecture ( CUDA ) extension. Successful exploitation can lead to an immediate denial of service or application instability. This vulnerability is tracked as CVE-2026-84286. Description An OOB memory access vulnerability exists in the exllamav3_ext module due to insufficient input validation. When the kernel parameter K is set to 0 in a crafted input, the extension generates a negative array index, resulting in a CUDA illegal memory access.s. The root cause is a missing bounds check in the kernel-table dispatch process. The checkpoint-derived block index ( cbi ) is used to access a fixed 24-entry array without confirming that either K or cbi fall within safe limits. Impact Primary impacts include Denial of Service (DoS) through process crashes and potential unstable execution states within applications utilizing the library.

Today, we’re making Cloudflare CASB more powerful than ever by introducing automatic remediation policies. This means security teams can now design event-driven logic to revoke risky file shares and dispatch custom webhooks, without manual intervention. When we launched Cloudflare CASB , a cloud access security broker, we wanted to provide security teams complete visibility into the posture of their SaaS applications before misconfigurations became incidents. With a quick, clientless integration, CASB surfaces risks like overshared files, dormant admin keys and tokens, OAuth apps with excessive permissions — continuously, across users in the organization. For years, SaaS Security Posture Management (SSPM) tools such as Cloudflare CASB have functioned as a passive alarm system. Most SSPM tools tell you what’s wrong but do not help you fix the issue, placing the burden on administrators to manage an ever-growing to-do list. A single misconfigured file-sharing policy across a Google Workspace tenant can generate thousands of findings in seconds, and even a disciplined team faces a window between detection and remediation measured in hours or days — more than enough time for a sensitive file to be downloaded, forwarded, or indexed. With automatic remediation policies, CASB customers can now configure the actions that should be invoked immediately after a new finding is identified. Shifting from reactive to proactive When we launched manual remediation actions earlier this year, we gave security teams the ability to resolve misconfigurations directly from the Cloudflare dashboard.

A few weeks ago I was browsing and got one of those "Verify you are human" Cloudflare popups. Except it wasn't Cloudflare — it was a ClickFix page that told me to press Win+R and paste a command. I'm on Linux so nothing executed on me, but I grabbed the file and spent time tearing it apart. Here's what's inside. **The file:** `Tourmaline.exe` (~10.8 MB) It's not a typical dropper. It's an Inno Setup 6.7.0 installer (Revision 2, 64-bit offsets — which broke every standard extraction tool I tried including innoextract) that bundles a full Python 3.11 runtime and two stages of obfuscated payload. **Stage 1 — Anti-sandbox time-lock** The first stage is a ~13 line obfuscated Python script with a clever trick: it counts down from 99,999,999 to find an XOR decryption key via brute force. On a sandbox with a 60-second timeout it never finishes. On a real machine it runs in seconds. I cracked it instantly using a known-plaintext attack on the first 4 bytes of the encrypted blob — recovered the key in O(1) without running the loop at all. **Stage 2 — Full Python RAT** Once decrypted, it's a hand-rolled Python backdoor with no external dependencies. Here's what it does: - **DNS tunneling** — all C2 traffic goes out as raw UDP DNS queries directly to `158.94.211.185:53`, disguised as `*.microsoft.com` lookups. Fully custom DNS packet builder, no library used. - **Blockchain dead-drop** — on startup it calls an Ethereum Sepolia smart contract (`0x2d7a04cca0c34005f58393f30ac725e25f19e5f5`) to get the current C2 IP, decrypted locally with a hardcoded ChaCha20 key. I verified this live — the contract returned the active IP. The attacker can update it any time, making IP blocklists useless. - **ECDSA-signed commands** — tasks from the C2 are P-256 signature verified before execution. You can't sinkhole it by intercepting the DNS tunnel. - **Arbitrary Python exec** — whatever the C2 sends back gets `exec()`'d in a persistent namespace. Full remote code execution. - **Persistence** as `TourmalineUpdate` in Task Scheduler, disguised as "Hardware monitoring service." Everything is in my GitHub repo — deobfuscated source, YARA rules, IOCs (JSON + CSV), and a decryption tool that reproduces the key recovery: **https://github.com/v-pun215/Tourmaline** Sample is included as a password-protected zip (`infected`) following the standard for sharing malware samples safely. Happy to answer questions on the methodology, especially the custom Inno Setup Revision 2 format parsing and the known-plaintext bypass.

1.1.1.1 now validates DNSSEC signatures made with ML-DSA-44 , a post-quantum signature algorithm standardized by the National Institute of Standards and Technology (NIST) . This is a first step toward preparing DNSSEC for a future in which today’s signature algorithms are no longer secure. Cloudflare plans to achieve full post-quantum security by 2029 . Much of the work so far has focused on TLS, but public-key cryptography is used in many other systems, including DNSSEC. While we began experimenting with post-quantum key agreement in TLS in 2019 and enabled support for all customers in 2022, post-quantum signatures have not yet received comparable testing in DNSSEC. There is also some urgency. Widespread client adoption of post-quantum TLS took years, partly because larger messages exposed assumptions and bugs in existing network software. That experience showed why early large-scale testing matters. We cannot wait until quantum computers become an immediate threat. The problem is that post-quantum signatures are large.
