Summary

Talishar is a fan-made Flesh and Blood project. Prior to commit 6be3871, a Path Traversal vulnerability was identified in the gameName parameter. While the application's primary entry points implement input validation, the ParseGamestate.php component can be accessed directly as a standalone script. In this scenario, the absence of internal sanitization allows for directory traversal sequences (e.g., ../) to be processed, potentially leading to unauthorized file access. This issue has been patched in commit 6be3871.
