Stored XSS via unsanitized hidden-album descriptions

Published Aug 30, 2026 · Updated Aug 30, 2026

Stored XSS in Coppermine Photo Gallery 1.6.0 through 1.6.28 allows remote authenticated users to inject script into hidden albums. The hidden-album update path in db_input.php stores an album description without neutralizing executable HTML or JavaScript before later rendering it. A low-privileged authenticated account must submit the description and a victim must view the affected album, allowing script execution in that victim's browser.
