Check if you are vulnerable description
PictShare versions before 3.7.1 generate file-deletion authorization tokens with a non-cryptographic random number generator. An attacker who can predict or infer its state may guess valid tokens and delete hosted files.
mitigation
Upgrade PictShare to version 3.7.1 or later.
