Since this is not a cloud service, remediation depends on the vendor releasing a patch. If you cannot patch yet, users should consider restricting access to the /api/fetch-metadata endpoint or implementing authentication and input validation to prevent SSRF attacks. Monitor vendor advisories for official patches or updates.
Description
Grimoire versions before 1.0.0 have an unauthenticated server-side request forgery (SSRF) vulnerability in the /api/fetch-metadata POST endpoint. This flaw allows attackers to submit arbitrary URLs that the server fetches and parses without authentication, potentially exposing internal or cloud metadata information. The vulnerability has a CVSS score of 5.8, indicating medium severity.
