CVE-2023-46951Public exploitNetwork attack vector

Session-data exposure via unescaped query parameter reflection

Published Mar 1, 2024 · Updated Apr 22, 2025

Reflected XSS in the sidekiq-unique-jobs Web UI 7.1.32 and earlier and 8.0.0 through 8.0.6 allows remote attackers to run scripts in users' browsers. The /changelogs, /locks, and /expiring_locks handlers reflect crafted filter query values into HTML without output encoding. Exploitation requires an authorized user to open a crafted link; injected script can read cookies, session data, or local storage in the mounted application's origin.
