Session data theft via unescaped filter parameters

Published Mar 1, 2024 · Updated Sep 16, 2024

Reflected XSS in Sidekiq 6.5.8 with sidekiq-unique-jobs allows remote attackers to execute browser script via crafted filter URLs. Filter parameters for the extension's /changelogs, /locks, and /expiring_locks routes enter rendered pages without HTML escaping. Exploitation requires a mounted web UI and an authorized user following a crafted link; the script runs in that user's origin and can read cookies, session data, or local storage.
