CVE-2026-25480 MEDIUM POC PATCH This Month

Cache poisoning in Litestar before 2.20.0 allows unauthenticated remote attackers to exploit improper Unicode normalization in the FileStore cache backend to create collisions between cache keys, enabling one URL to serve another URL's cached responses. Public exploit code exists for this vulnerability. An attacker can leverage this to serve malicious cached content to users accessing legitimate endpoints.

CVE-2026-23950 HIGH POC PATCH This Week

Symlink poisoning via race condition in node-tar up to version 7.5.3 allows attackers to exploit Unicode normalization on case-insensitive filesystems like macOS APFS, where the path reservation system fails to serialize operations on colliding paths. Public exploit code exists for this vulnerability, enabling concurrent processing that bypasses internal safeguards. Node.js users and applications depending on vulnerable tar versions should update immediately, as attackers can leverage this to manipulate file operations during archive extraction.
