Description
Webasyst Framework through 4.4.0 contains a cross-site request forgery vulnerability in the Photos app that allows remote attackers to perform backend actions because the app does not enable the framework's opt-in CSRF check. Attackers can lure logged-in Photos users to a malicious page that submits forged POST requests to photo/delete, album/save, photo/manageAccessSave or photo/saveField, deleting photos and changing access rights.
