CVE-2025-28857Network attack vector

Stored XSS via forged administrator request

Published Mar 11, 2025 · Updated Apr 28, 2026

Stored XSS in Rankchecker.io Integration 1.0.9 and earlier allows remote attackers to persist script through forged requests. The public CNA and Patchstack records identify a CSRF-to-stored-XSS chain but do not disclose the affected handler, parameter, or missing validation operation. Exploitation requires an authenticated administrator to visit attacker-controlled content, after which the stored script runs in a victim's browser with the site's origin.
