A missing authentication check in the deleteShareLink endpoint (POST /api/file/deleteShareLink.php) allows any unauthenticated client to delete arbitrary share links by supplying only the share token. This results in a denial of service to users who rely on those links, effectively revoking access to shared files. The vulnerability is a classic Missing Authentication flaw (CWE\u2011306).", "risk_and_exploitability": "The CVSS score is 3.7, indicating low severity. EPSS is not available and it is not listed in the KEV catalog, suggesting no known large\u2011scale exploitation yet. The attack vector is network: an anonymous HTTP client can simply send a POST request to the exposed endpoint with a valid share token. The risk is primarily availability: the deletion of share links disrupts file sharing but does not compromise confidentiality or integrity. Nevertheless, any organization that relies on FileRise should deploy the fix promptly."}}}}, "created": "2026-03-20T10:36:36.500660+00:00", "updated": "2026-03-20T10:36:36.500688+00:00", "vendors": []}
