This Server\u2011Side Request Forgery can read internal services, enumerate the local network, or harvest cloud metadata such as AWS or GCP IAM tokens, enabling data exfiltration or privilege escalation.

No EPSS value is provided, but the lack of a patch and the open nature of the endpoint suggest a high likelihood of exploitation if an attacker discovers it. As the vulnerability is not yet listed in CISA\u2019s KEV catalog, widespread exploitation may be limited, yet the potential to access sensitive data remains significant. Attackers can trigger the SSRF simply by sending HTTP POST requests to the exposed endpoint from any location with network reach to the server, bypassing authentication entirely."}}}}, "created": "2026-03-25T11:47:03.198760+00:00", "updated": "2026-03-25T20:49:48.858614+00:00", "vendors": ["parisneo", "parisneo$PRODUCT$lollms-webui"]}
