Description

PictShare before version 3.7.1 contains a weak randomness vulnerability where the getRandomString() function uses the non-cryptographic rand() PRNG to generate the delete_code authorization token in src/inc/core.php. Attackers can predict or infer the PRNG state to guess valid delete_code values and perform unauthorized deletion of hosted files without needing to read the code from the info endpoint.
