Alert meAnalysisAIv1 – Sep 15, 2026
Authentication bypass in IBM WebSphere Application Server 8.5 and 9.0 allows an unauthenticated attacker positioned on an adjacent network segment to reach request-handling functionality that performs no authorization check (CWE-862) and read sensitive information from the response. IBM has released a vendor patch, and there is no public exploit code or CISA KEV entry associated with this issue at time of analysis, so exploitation is not confirmed actively exploited. CVSS rates it 6.5 with confidentiality-only impact and PR:N/UI:N, but no EPSS score was supplied, leaving real-world exploitation likelihood unquantified.
