Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Cotonti's Personal File Storage (PFS) module, in Packagist package cotonti/cotonti at versions up to and including 1.0.0, is affected. The file upload action does not check the anti-CSRF token, so a remote attacker who tricks a logged-in user into opening a malicious page can make the user's browser upload arbitrary files into that user's PFS storage. No fixed version is listed in the source.
