Stored cross-site scripting via unencoded album metadata

Published Jul 20, 2023 · Updated Aug 2, 2024

Stored cross-site scripting in Boom CMS 8.0.7 allows remote authenticated users to execute script in another user's browser via album metadata. The assets-manager album add function stores title and description values and renders them in frontend and backend album views without effective output encoding. A low-privileged account must create a malicious album, and execution occurs when another user previews the affected album or asset listing.
