Official Description
IBM WebSphere Application Server - Liberty 17.0.0.3 through 26.0.0.3 IBM WebSphere Application Server Liberty is vulnerable to server-side request forgery (SSRF). This may allow remote attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks.
Technical Analysis
CVE-2026-1561 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
