TL;DR

• •CISA has added a Cisco Catalyst SD-WAN Manager information disclosure vulnerability (CVE-2026-20133) to its KEV Catalog, mandating federal agencies patch by April 24th due to active exploitation.
• •The flaw allows unauthenticated remote attackers to access sensitive information on unpatched devices, stemming from insufficient file system access restrictions.
• •While CISA confirms active exploitation, Cisco's advisory currently states it's unaware of public announcements or malicious use, highlighting a critical intelligence gap for network defenders.

TL;DR

• •A new vulnerability, 'RedSun', has been disclosed affecting Windows 10, 11, and Server.
• •The vulnerability impacts system user access with the April 2026 Update.
• •Details about the exact nature of the vulnerability are limited; further investigation is needed.

TL;DR

• •Dozens of WordPress plugins have been compromised with backdoors.
• •Thousands of websites are potentially affected, creating a significant security risk.
• •Immediate action is needed to scan for and remove compromised plugins and harden WordPress security.

TL;DR

• •Anthropic's Claude Code AI successfully discovered multiple remotely exploitable security vulnerabilities in the Linux kernel.
• •One critical bug in the Network File System (NFS) driver remained hidden for an astonishing 23 years, demonstrating the AI's deep understanding.
• •The discovery was made with surprisingly little human oversight, using a simple script to 'point' Claude at kernel source files and ask it to find vulnerabilities as if in a CTF.
• •This breakthrough highlights the immense potential of large language models (LLMs) in automating complex vulnerability research and enhancing software security.
