In late November 2025, developers and API users of ChatGPT and OpenAI’s platform received a note that felt personal: an alert about a data exposure linked not to OpenAI’s own servers but to a third-party analytics vendor. That vendor was Mixpanel.

A critical vulnerability, CVE-2025-66516 (CVSS 10.0), has been identified in Apache Tika, affecting how the framework processes PDF files containing XFA (XML Forms Architecture) data. The vulnerability resides in tika-core, which means any system using Tika’s default parsing behavior remains vulnerable even if the PDF parser module was previously patched. No special configuration or insecure application code is required; simply ingesting a malicious PDF is enough to trigger the exploit.

Critical vulnerabilities in React Server Components (CVE-2025-55182) and Next.js (CVE-2025-66478) enable unauthenticated remote code execution in default configurations. The flaw resides in the "Flight" protocol used for server-side rendering, making it a sought after target for adversaries looking to bypass standard controls. While the public discourse is currently cluttered with unreliable exploits, we need to ground our defense in verifiable network evidence.

A Critical Remote Code Execution (RCE) vulnerability, identified as CVE-2025-55182, has been discovered in Next.js applications utilizing React Server Components (RSC) and Server Actions. This vulnerability stems from insecure deserialization within the underlying “Flight” protocol used by React. Unauthenticated remote attackers can exploit this flaw to execute arbitrary code on the server, potentially leading to a complete compromise of the application and underlying system.

Many organizations set remediation SLAs, but static severity-based timelines and manual tracking prevent them from meeting those deadlines in a way that meaningfully reduces risk. This article outlines how automated, risk-based SLAs connect timelines to real exploitability, exposure, and asset value, turning deadlines into reliable, measurable outcomes. Key takeaways from this article.

While the world worries about "jailbreaking" LLMs or preventing them from hallucinating, a critical new vulnerability has just reminded us of a fundamental truth: AI is just software, and software has bugs. A newly discovered critical flaw (CVE-2025-62164) in vLLM, one of the most popular libraries for serving large language models, allows attackers to achieve Remote Code Execution (RCE) or crash servers simply by sending a malicious API request. This isn't a failure of the AI model.

On December 3, 2025, the React team disclosed CVE-2025-55182, a critical remote code execution vulnerability in React Server Components. The flaw carries a CVSS score of 10.0, the maximum severity rating. What makes this vulnerability particularly dangerous is its simplicity: attackers only need to send a single crafted HTTP request to gain complete control over vulnerable servers. No authentication required. No complex exploit chains. Just one malicious request.
