Cloudflare Sep 3

Your scanner just flagged 4,000 new vulnerabilities, 78 of them critical. Which one do you fix first? To answer that question, Cloudflare is announcing early access to Vulnerability Discovery and Remediation, now part of Cloudflare Managed Defense . Vulnerability Discovery and Remediation is a new, invitation-only Cloudflare service that helps customers detect and mitigate vulnerabilities in their codebases. Through the OpenAI Daybreak Defense Network , we use OpenAI Daybreak models, including GPT-5.6 Cyber, for reconnaissance, hunting, and validation against codebases that you authorize us to access. If we detect a vulnerability, we will then propose solutions to you, automatically checking each proposed patch and any accompanying proposed mitigation before presenting them for review. Importantly, you are in the driver’s seat: while we may propose code patches and other mitigations, you decide whether they are implemented. Choosing what to fix first has always been hard. It's getting harder. Large language models can now surface weaknesses across a codebase in minutes , which means the number of findings keeps climbing. But the real problem is speed. Attackers can use AI to accelerate parts of vulnerability discovery and exploitation, giving security teams and developers less time to decide what matters and act on it. Imagine that your scanner tells you there's a vulnerability in a handler. It doesn't tell you whether that code is deployed. It doesn't tell you whether anyone is actually hitting that route, what security activity surrounds it, or what controls you already have

Every time Cloudflare opens a new TLS 1.3 connection to an origin server, we have to make a guess: the protocol requires us to commit to a key agreement algorithm in the very first packet we send, before the origin has told us anything about itself or what it can support. If we guess right, the handshake completes in one round trip. Guess wrong, and the origin replies with a HelloRetryRequest , we start over, and the connection costs two round trips. For years, our guess was the same for every origin on the Internet: X25519 . Widely supported, but as it turns out, suboptimal for roughly 30% of the origin connections we've since measured. Today we're announcing Automatic Key Exchange , an extension of Automatic SSL/TLS that replaces the guess with a measurement. We probe each origin to learn which key agreement algorithms it supports and prefers, then lead with that algorithm on the first try, preferring the post-quantum hybrid X25519MLKEM768 wherever the origin can speak it. With the ongoing rollout of Automatic Key Exchange across origin connections, HelloRetryRequests fell from roughly 52% to 3.7%, cutting more than 150 ms off connection handshake latency at p90. In addition, as part of our ongoing rollout, hundreds of thousands of domains now

Many healthcare organizations have been told that HIPAA requires an annual penetration test. The current rule is more nuanced. Penetration testing for HIPAA compliance is not prescribed as one universal annual obligation, but regulated entities must conduct a comprehensive risk analysis, manage identified risks, and evaluate whether their safeguards remain effective. A well-scoped pentest can provide important evidence supporting those responsibilities. HHS has also proposed making annual penetration testing explicit, although that proposal is not yet binding. The post HIPAA Penetration Testing Requirements for Healthcare Enterprises appeared first on Synack .

During my research into model alignment, I noticed how frequently safety guardrails cause false positive refusals on legitimate cybersecurity tasks. To address this, I applied directional abliteration to Qwen3-4B. By locating the specific internal activation pattern responsible for refusal and removing it directly from the model weights, I neutralised the refusal response entirely. \[model : [https://huggingface.co/IamLucif3r/Qwen3-4B-Instruct-2507-Abliterated](https://huggingface.co/IamLucif3r/Qwen3-4B-Instruct-2507-Abliterated) \] The process requires no fine tuning, no datasets and preserves the model's original reasoning and coding performance. You can run it using ollama : `ollama run` [`hf.co/IamLucif3r/Qwen3-4B-Instruct-2507-Abliterated:Q4_K_M`](http://hf.co/IamLucif3r/Qwen3-4B-Instruct-2507-Abliterated:Q4_K_M) What this modification provides: * Direct, unhindered analysis of exploit payloads, binaries and source code. * Complete removal of conversational lecturing and moral disclaimers * Baseline benchmark capabilities intact without catastrophic forgetting. I have documented the complete methodology, findings & technical setups in my article: [https://blog.anmolsinghyadav.com/llm-abliteration-refusal-guardrails-f227460e2c7c](https://blog.anmolsinghyadav.com/llm-abliteration-refusal-guardrails-f227460e2c7c) You can create your own abliterated model.

Many still view logic programming languages like Prolog as purely academic or limited to classic AI. However, in my latest "Hyper Chaos Stress Test (v7.0 God Mode)" benchmarking a custom web application firewall (WAF) engine, this architecture proved to be an absolute powerhouse for high-throughput cyber defense.  When hit with 40,000 Active Hyper Chaos Waves against an intelligence feed database containing 276,717 clauses, the engine maintained a flawless "100% METAL LOCKED SECURE! SHIELD IS IMPENETRABLE" verdict, bypassing exactly 0 unique payloads.  Here is the raw performance data extracted directly from the SWI-Prolog virtual machine execution: * Total Inferences Executed: 100,201,875 logical reasoning steps inside the main memory. * Peak Induction Speed: 7,024,009 LIPS (Logical Inferences Per Second). * Volatile RAM Footprint: \~4.2 MB (4,270 KB allocated, 3,754 KB in use), running ultra-lightweight on a standard 8.0 GB system. * Garbage Collection Overhead: 7 core and 24 clause garbage collections completed in 0.000 pure seconds. * JIT Hashing Performance: Scaled automatically to 276,717 JITI Rules across 4,096 memory buckets, locking in an absolute 2,538.4x Speedup Factor.  The Secret? Just-In-Time Indexing (JITI). Instead of checking criteria sequentially (linear scanning), SWI-Prolog dynamically constructs deep hash tables for the active rule sets. The engine instantly jumps to the exact memory location matching the payload signature, yielding a massive 2,538x speedup.  This proves that declarative logic programming isn't just mathematically sound—it is highly production-viable, offering incredible protection while slashing cloud compute infrastructure costs down to the absolute bare minimum.  check detail hure : [**https://github.com/lokinpendawa/aethel\_core**](https://github.com/lokinpendawa/aethel_core) What are your thoughts on utilizing declarative logic programming for modern, low-footprint cybersecurity perimeters?

CVE

Overview Casdoor is an open-source Access Management (IAM) platform used to manage web applications. An authorization bypass vulnerability affects Casdoor versions 3.115.0 and earlier. The vulnerability allows a non-global organization administrator to perform unauthorized administrative actions against arbitrary organizations by exploiting inconsistent object resolution between the authorization layer and downstream controllers. In multi-tenant deployments, an attacker with administrative privileges within a single organization can bypass tenant isolation and perform administrative operations against other organizations. Description CVE-2026-15630. The vulnerability stems from a desynchronization between authorization and action in multiple POST /api/{add,delete}- endpoints (e.g., /api/add-user, /api/delete-user, /api/add-permission) . While the global authorization filter ( routers/authzfilter.go ) correctly uses the ?id= URL query parameter as the authoritative target for authorization decisions, the affected controllers ( controllers/user.go , controllers/permission.go , etc.) ignore ?id= and operate solely on the owner and name fields in the JSON request body. As a result, authorization is evaluated against one object while the requested operation is executed against another, allowing an authenticated organization administrator ( IsAdmin=true ) to perform unauthorized administrative actions across tenant boundaries. Impact An attacker with administrative privileges in a single organization can compromise the isolation guarantees of a multi-tenant Casdoor deployment. Depending on the exposed endpoints and de

While the full implementation of the Cyber Resilience Act (CRA) won’t take effect until December 2027, another critical milestone is already approaching much sooner. Starting from 11 September 2026 , all manufacturers selling products with digital elements in countries of the European Union will be required to report actively exploited vulnerabilities in their digital products, as well as related security incidents, as well as security incidents that affect or compromise products already placed on the market. Incidents or vulnerabilities limited to development or internal environments are therefore only relevant if they result in (or could result in) a compromise of production devices. Although the platform itself is not yet available, the landmark legislation has already established a detailed framework and set of requirements. This article aims to summarize the most important aspects of the reporting process in order to help you prepare for these upcoming changes. Additionally, it provides clear guidelines for determining when a vulnerability or incident becomes mandatory to report. Overview In Chapter I, Article 14, §1, the Cyber Resilience Act states the following: A manufacturer shall notify any actively exploited vulnerability contained in the product with digital elements that it becomes aware of simultaneously to the CSIRT designated as coordinator, in accordance with paragraph 7 of this Article, and to ENISA. In the context of the CRA, an “ actively exploited vulnerability ” is defined as a “vulnerability for whic
