EPSS data is not available and the vulnerability is not listed in the CISA KEV catalog, indicating no known widespread exploitation yet.

The path traversal bypass is straightforward once the attacker knows the weak filter, so the attack vector is local with limited privilege escalation beyond the existing administrator role."}}}}, "created": "2026-04-20T18:45:14.227087+00:00", "updated": "2026-04-22T11:47:38.064822+00:00", "vendors": ["openmage", "openmage$PRODUCT$magento"]}
