The EPSS score is below 1%, suggesting a low likelihood of exploitation in the near term. The failure is not listed in the CISA KEV catalog, so there is no evidence of active exploitation. The attack vector requires the attacker to be an authenticated user, so the adversary must first compromise user credentials or gain legitimate access to the system. Once authenticated, the attacker can exploit the fax endpoint to exfiltrate any filepath supplied."}}}}, "created": "2026-03-02T12:07:06.838325+00:00", "updated": "2026-04-16T15:30:06.226284+00:00", "vendors": ["openemr", "openemr$PRODUCT$openemr"]}
