Cybersecurity research firm Xint on Monday published details of a bug in the OpenAI API that leaks raw reasoning traces from frontier OpenAI models, revealing the risk of other data leaks. OpenAI has confirmed the flaw, mitigated it, and paid a bug bounty for its discovery. The problem is that OpenAI had already deployed mitigations for the issue in August after a research report dubbed Stolen Thoughts revealed a sim…
Researchers have demonstrated remote code execution through CVE-2026-111497, an out-of-bounds write in Google's Brotli decoder library, and public proofs-of-concept (PoCs) are available. Software that uses the decoder includes Node.js, .NET, Bun, Envoy Proxy, Istio, Python HTTP clients and PHP for Windows.Key TakeawaysCVE-2026-111497, known as Brotli2Shell and by several other names, is an out-of-bounds write in Goog…

Overview Fireblocks' mpc-lib library contains a cryptographic fail-open vulnerability in its BIP32 hardened derivation implementation in the case of a missing private parent key. This breaks the ancestor isolation property of hardened derivation, allowing an attacker with a compromised lower-level signer share to recover the higher-level share it was derived from. Description Fireblocks is a digital-asset custody and…
Learn how to use Tenable solutions to find vulnerable PHP versions, prioritize remediation, and patch the critical PHP2Shell vulnerabilities (CVE-2026-109618 and CVE-2026-109619) faster.Key takeawaysThe PHP2Shell vulnerabilities (CVE-2026-109618 and CVE-2026-109619) put security teams in a race against attackers. PHP runs on more than 70% of websites, so organizations need to quickly find where they’re affected and u…
Overview vsomeip, COVESA's open source implementation of the SOME/IP automotive communication middleware, contained a memory allocation vulnerability present in versions 3.7.3 and below. A vsomeip reliable (TCP) SOME/IP endpoint grows its receive buffer to an attacker-declared message size before validating that the declared bytes have actually been received, allowing a remote, unauthenticated peer to exhaust host me…
PHP has rebuilt its official Windows packages for PHP 8.2 through 8.5 to fix CVE-2026-111497, a flaw in the Brotli compression library that the packages include. The flaw can let an attacker corrupt memory and potentially run code. PHP says the flaw can be reached through the cURL extension when the extension decompresses HTTP responses automatically. cURL leaves that off by default, but
OverviewOn October 21, 2026, the Node.js Project published a security advisory for CVE-2026-111497, an out-of-bounds write in the Brotli decoder bundled with Node.js. The vulnerability affects the Node.js 26.x, 24.x, and 22.x release lines. Node.js rates the issue High, while Google, the CVE Numbering Authority (CNA), gives it a critical CVSSv4 score of 9.2.An attacker who can supply Brotli data that an application d…
Executive Summary: What are CVE-2026-109618 and CVE-2026-109619? Why PHP vulnerabilities put most of the web at risk When you open a web page, something has to build that page before it reaches you. For roughly seven out of ten websites, the software doing that job is PHP. It sits on the web server, assembles the […]
