An attacker can therefore supply URLs such as http://169.254.169.254/latest/meta-data/, http://192.168.x.x/, or http://127.0.0.1/, causing the server to reach internal network resources or cloud instance metadata. The attack is blind; while no response is returned directly to the attacker, timing differences and error logs can be leveraged to infer whether the request succeeded, enabling internal enumeration and potentially facilitating more serious attacks.", "risk_and_exploitability": "With a CVSS score of 9.3 the risk is considered critical. EPSS data is not available, and the vulnerability is not listed in the CISA KEV catalog. Attackers would simply need to send a crafted GET request to getImage.php or getImageMP4.php, which are publicly reachable without authentication. Because the flaw is a blind SSRF, detection requires monitoring of timing or logs, but once discovered it can expose internal services or metadata, creating a foothold for further exploitation."}}}}, "created": "2026-03-20T08:52:33.803700+00:00", "updated": "2026-03-20T10:37:15.489774+00:00", "vendors": ["wwbn", "wwbn$PRODUCT$avideo-encoder"]}
