Description
### Summary In `torrentpier/library/includes/functions.php`, `get_tracks()` uses the unsafe native PHP serialization format to deserialize user-controlled cookies: https://github.com/torrentpier/torrentpier/blob/84f6c9f4a081d9ffff4c233098758280304bf50f/library/includes/functions.php#L41-L60 ### PoC One can use [`phpggc`](https://github.com/ambionics/phpggc/) and the chain `Guzzle/FW1` to write PHP code to an arbitrary file, and execute commands on the system. For instance, the cookie `bb_t` will be deserialized when browsing to `viewforum.php`.
