Server-Side Request Forgery (SSRF) in IBM WebSphere Application Server Liberty - CVE-2026-1561

Vulnerability identifier: #VU124833

CSH Severity: Low

CVSS v4: 2.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N]

CVE-ID: CVE-2026-1561

CWE-ID: CWE-918

Exploitation vector: Remote access

Exploit availability: No public exploit available

The disclosed vulnerability allows a remote user to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input when the samlWeb-2.0 feature enabled. A remote user can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
