HIGHNVD 7.57.5—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 0.7%, top 50% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
