xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: out-of-bounds read/write in GLX ChangeDrawableAttributes

An out-of-bounds read flaw was found in the X.Org X server and Xwayland in glXDispChangeDrawableAttributes. A wrong size validation check can read a client-controlled number of bytes, exceeding the request buffer, leading to information disclosure. A write path also exists but requires byte-swapp...

CVE-2026-62314

Anubis Web AI Firewall Utility vulnerable in versions 1.22.0–1.26.0-pre1 due to PathChecker.Check() trusting the client-controlled X-Original-URI header before r.URL.Path, enabling bypass of the challenge via ALLOW rules (e.g., ^/.well-known/.*$).
