RomM (ROM Manager) allows users to scan, enrich, browse and play their game collections with a clean and responsive interface. In versions 4.0.0-beta.3 and below, an authenticated arbitrary file write vulnerability exists in the /api/saves endpoint. This can lead to Remote Code Execution on the system. The vulnerability permits arbitrary file write operations, allowing attackers to create or modify files at any filesystem location with user-supplied content. A user with viewer role or Scope.ASSETS_WRITE permission or above is required to pass authentication checks. The vulnerability is fixed in version 4.0.0-beta.4.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
