CVE-2023-22475Network attack vector

JavaScript execution via unescaped trigger parameters

Published Jan 6, 2023 · Updated Mar 10, 2025

Stored XSS in Thinkst Applied Research Canarytokens before sha-fb61290 allows remote attackers to run JavaScript via an HTTP token trigger. The history page rendered attacker-controlled trigger parameters through a Jinja environment without autoescaping. Exploitation requires discovery of the token URL and a later history-page visit by its creator; impact is limited to that token's history and management actions.
