IBM disclosed CVE-2026-10842, a high-severity vulnerability with CVSS 7.5 that could let remote attackers bypass security constraints in WebSphere Application Server 8.5, 9.0, and Liberty 17.0.0.3 through 26.0.0.7. The flaw, classified as Authentication Bypass by Alternate Name, was published to the NVD on July 30, 2026.
The description states that a remote attacker could exploit the vulnerability to bypass security constraints, potentially exposing confidential data given the high confidentiality impact.
Organizations running the listed versions of WebSphere Application Server should consult the IBM support page immediately.
Enterprise teams still running older WebSphere 8.5 and 9.0 instances face immediate exposure; patching or migration to a fixed release should be prioritized given the network-accessible nature of the bypass.
