CVE-2026-41250Public exploitNetwork attack vector

Session-token theft via unsafe confirmation rendering

Published May 11, 2026 · Updated May 11, 2026

Stored cross-site scripting in Taiga Front before 6.9.1 allows remote authenticated users to execute JavaScript in another user's browser. ConfirmService passes a crafted issue or user-story title through textToHTML and inserts the result into confirmation dialogs with .html(). A low-privilege user can store the payload, but a victim must open the affected deletion confirmation and interact with its rendered content; the script can read the session token held in local storage.
