CVE-2024-28853Public exploitNetwork attack vector

Browser script execution via unsanitized admin preferences

Published Mar 27, 2024 · Updated Aug 29, 2024

Stored XSS in Ampache before 6.3.1 allows remote authenticated users to run script in another user's browser via admin preferences. The admin preference update handler stores crafted values for api_hidden_playlists, libitem_browse_alpha, custom_blankalbum, custom_blankmovie, and similar fields without neutralizing HTML attribute content. Administrator privileges are required to save the payload, and a victim must render the stored preference value; script execution is confined to the victim's browser context.
