Deeper analysis

RomM, also known as ROM Manager, is an open-source tool for scanning, enriching, browsing, and playing game collections. Versions 4.0.0-beta.3 and earlier contain an authenticated arbitrary file write flaw in the /api/saves endpoint that permits an attacker to create or overwrite files at arbitrary filesystem paths with attacker-supplied content, directly enabling remote code execution. The issue is tracked as CWE-434 and carries a CVSS 4.0 score of 9.4.

An attacker who has already obtained a viewer role or the Scope.ASSETS_WRITE permission can send crafted requests to the affected endpoint and place executable payloads or configuration files anywhere on the host filesystem, achieving full system compromise without further user interaction.

The vulnerability is resolved in version 4.0.0-beta.4; the project’s security advisory and the associated commit on GitHub document the fix and recommend that administrators upgrade immediately. The EPSS score remains flat at 0.0307 with no observed increase after disclosure.
