CVEPhishing

Overview The UEFI Shell program may expose raw memory access capabilities that, if present in platform firmware for debugging or advanced support use cases, could be abused to undermine UEFI Secure Boot protections. When the UEFI Shell is included in SPI flash, an attacker with the ability to modify UEFI boot configuration may be able to create multiple boot option entries and bypass controls intended to prevent the UEFI Shell from launching while Secure Boot is enabled. This could allow an attacker to modify the pre-boot environment and execute unauthorized software during system startup. Description The Unified Extensible Firmware Interface (UEFI) is a firmware specification that defines the interface between a computing platform's hardware and operating system (OS) during the early boot process before the operating system is loaded. UEFI Secure Boot helps ensure that only trusted and digitally signed software is executed during these early stages of platform initialization. The TianoCore EDK II project provides an open-source reference implementation of the UEFI and Platform Initialization (PI) specifications. The project includes the UEFI Shell , which provides command-line utilities for debugging, diagnostics, and advanced platform management. Many OEM and Independent BIOS Vendor (IBV) firmware implementations include the UEFI Shell in SPI flash for service and support purposes. Because the shell executes in the pre-boot environment, it provides powerful commands such as dmem (display memory) and mm (memory modify) that can access physical memory. Many implementations include a boot entry for the

Overview Skullcandy Dime 3 wireless earbuds, running firmware version 1.0.0.28, accept a new Bluetooth Classic (BR/EDR) pairing request from an unpaired device without requiring the earbuds to be placed into pairing mode or requiring any physical confirmation or interaction from the owner. Description The Skullcandy Dime 3 (Model S2DCW) wireless earbuds, running firmware version 1.0.0.28, accept a new Bluetooth Classic (BR/EDR) pairing request from a previously unpaired device without the device being placed into pairing mode by the owner and without physical confirmation on the earbuds. The device's Bluetooth PnP modalias identifies the chipset vendor as Airoha Technology Corp. (Bluetooth SIG company ID 0x0094). This vulnerability was previously disclosed in CVE-2025-20701 and is described as: In the Airoha Bluetooth audio SDK, there is a possible way to pair Bluetooth audio device without user consent. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. An attacker is required to be within Bluetooth radio range to the target earbuds, but no prior pairing, physical access, or interaction with the earbuds' buttons or case is required to exploit the vulnerability. A direct pairing request to the earbuds' known or discovered Bluetooth Classic address can be sent without a PIN, passkey, or physical confirmation. The pairing/bonding completes without owner action due to the device's NoInputNoOutput I/O capability. The firmware version displayed on the affected Skullcandy Dime 3 wireless earbuds is 1.0.0.28. Impact Once bonded, the attacker's device is added as a trusted device and can reconnect automatically whenever in range. This allows an attacker to est

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.

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

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.
