CVE-2025-46550Public exploitNetwork attack vector

Session hijacking via unvalidated idformulaire reflection

Published Apr 29, 2025 · Updated Apr 30, 2025

Reflected XSS in the BazaR endpoint in YesWiki before 4.5.4 allows remote attackers to execute script through a crafted idformulaire value. The forms_confirm.twig template inserts request.get.idformulaire into a translated alert message and generated URL without converting the value to the expected integer. A user must open a crafted link; the script then runs in that user's browser and can steal a session cookie or alter rendered page content.
