NIST to stop rating non-priority flaws due to volume increase
The National Institute of Standards and Technology will stop assigning severity scores to lower-priority vulnerabilities due to the growing workload from rising submission volumes. Starting April 15, the service will only analyze and provide additional details (e.g., severity rating, product lists) for security issues that meet specific criteria related to the risk they pose. The […]
Critical flaw in Protobuf library enables JavaScript code execution
Proof-of-concept exploit code has been published for a critical remote code execution flaw in protobuf.js, a widely used JavaScript implementation of Google’s Protocol Buffers. The tool is highly popular in the Node Package Manager (npm) registry, with an average of nearly 50 million weekly downloads. It is used for inter-service communication, in real-time applications, and for […]
Critical Nginx UI auth bypass flaw now actively exploited in the wild
A critical vulnerability in Nginx UI with Model Context Protocol (MCP) support is now being exploited in the wild for full server takeover without authentication. The flaw, tracked as CVE-2026-33032, is caused by nginx-ui leaving the ‘/mcp_message’ endpoint unprotected, allowing remote attackers to invoke privileged MCP actions without credentials. Because those actions involve writing and […]
CISA flags Windows Task Host vulnerability as exploited in attacks
CISA warned U.S. government agencies to secure their systems against a Windows Task Host privilege escalation vulnerability that could allow attackers to gain SYSTEM privileges. Task Host is a core Windows system component that serves as a container for DLL-based processes, allows them to operate in the background, and ensures they close properly during shutdown […]

Critical flaw in wolfSSL library enables forged certificate use
A critical vulnerability in the wolfSSL SSL/TLS library can weaken security via improper verification of the hash algorithm or its size when checking Elliptic Curve Digital Signature Algorithm (ECDSA) signatures. Researchers warn that an attacker could exploit the issue to force a target device or application to accept forged certificates for malicious servers or connections. […]
Adobe rolls out emergency fix for Acrobat Reader zero-day flaw
Adobe has released an emergency security update for Acrobat Reader to fix a vulnerability, tracked as CVE-2026-34621, that has been exploited in zero-day attacks since at least December. The flaw allows malicious PDF files to bypass sandbox restrictions and invoke privileged JavaScript APIs, potentially leading to arbitrary code execution. The exploit observed in attacks enables reading and stealing arbitrary files. No user […]
Critical Marimo pre-auth RCE flaw now under active exploitation
Hackers started exploiting a critical vulnerability in the Marimo open-source reactive Python notebook platform just 10 hours after its public disclosure. The flaw allows remote code execution without authentication in Marimo versions 0.20.4 and earlier. It tracked as CVE-2026-39987 and GitHub assessed it with a critical score of 9.3 out of 10. According to researchers at cloud-security […]
13-year-old bug in ActiveMQ lets hackers remotely execute commands
Security researchers discovered a remote code execution (RCE) vulnerability in Apache ActiveMQ Classic that has gone undetected for 13 years and could be exploited to execute arbitrary commands. The flaw was uncovered using the Claude AI assistant, which identified an exploit path by analyzing how independently developed components interact. Tracked as CVE-2026-34197, the security issue received […]
