It allows a remote attacker to cause the application server to send arbitrary HTTP requests to internal or external resources. This can lead to network enumeration, discovery of hidden services, or enable other attacks that depend on the information or access obtained. The weakness is identified as CWE\u2011918.", "risk_and_exploitability": "The CVSS score of 5.4 indicates moderate severity. The EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog. The described SSRF can be triggered remotely, likely by sending crafted requests to the Liberty server over HTTP or HTTPS. Because the vulnerability allows an attacker to issue outgoing requests without authentication, the risk is significant for systems that rely on internal network isolation. Mitigation is recommended as soon as possible."}}}}, "created": "2026-03-25T21:46:17.242146+00:00", "updated": "2026-03-26T11:33:59.675941+00:00", "vendors": ["ibm", "ibm$PRODUCT$websphere_application_server"]}
