Alert meAnalysisAIv1 – Sep 15, 2026
Authorization bypass in IBM WebSphere Application Server 8.5 and 9.0 lets an attacker positioned on an adjacent network segment reach functionality without the required authorization checks, resulting in limited (low) confidentiality exposure with no integrity or availability impact. The published CVSS 3.1 score is only 3.1 (AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N), reflecting that exploitation demands network adjacency and a high-complexity precondition rather than an internet-facing attack. There is no CISA KEV listing, no public exploit code identified in the provided sources, and an EPSS score was not supplied; IBM has published a fix. Note the tension between the 'authorization bypass' label and the very low scored impact — the advisory's own severity framing should be verified directly against the IBM support page.
