Browser script execution via unencoded content fields

Published May 7, 2025 · Updated May 8, 2025

Stored and reflected XSS in Koillection 1.6.10 allows remote attackers to execute script in a user's browser through crafted fields. Collection and item text fields store unencoded HTML that runs when a shared link is viewed, while wishlist and album creation reflect the same input. Exploitation requires creating or editing affected content and a browser trigger; stored payloads can reach other users, but the documented reflected paths affect only the author and HttpOnly cookies block direct session-cookie theft.
