CVE-2026-105118: Openidentityplatform Openam

Medium severity, CVSS 4.7. EPSS: 0.1% chance of exploitation in the next 30 days.

OpenAM before 16.1.3 contains an open redirect vulnerability that allows unauthenticated attackers to redirect users by supplying an unverified id_token_hint to the /oauth2/connect/endSession endpoint. Attackers can name any realm client in a forged hint to redirect victims to any registered post-logout URI, enabling phishing that borrows the OpenAM host's trust.
