Unauthenticated gallery deletion via unchecked folder parameter
Published Jun 25, 2026 · Updated Jun 25, 2026
Missing authorization in JoomlaWorks K2 1.0 through 2.26 allows remote attackers to delete gallery folders through a frontend request. The frontend item.checkin task passes the unauthenticated sigProFolder query parameter directly into the path addressed by JFolder::delete beneath the K2 gallery media directory. No account or user interaction is required; the documented consequence is unauthorized deletion within the K2 gallery media tree, not host-wide file deletion.
