CVE-2025-53310Network attack vector

Reflected XSS via missing nonce validation

Published Jun 27, 2025 · Updated Apr 28, 2026

Cross-site request forgery in Funnnny HidePost 2.3.8 and earlier allows remote attackers to trigger reflected XSS through a crafted request. Public records do not identify the affected function; they state that missing or incorrect nonce validation lets a cross-origin request trigger reflected script output. Exploitation requires a privileged user to visit a crafted page or link, after which script runs in that user's browser context.
