CVE-2025-8662Network attack vector

SAML IdP disruption via cache modification

Published Sep 2, 2025 · Updated Sep 3, 2025

Improper input validation in Open Identity Platform OpenAM 14.0.0 through 14.0.1 allows remote authenticated users to interrupt its SAML IdP. The SAML IdP request path fails to validate a request parameter before using it to modify OpenAM's internal cache; the exact function is undisclosed. Exploitation requires low-privileged authentication and a deployment with multiple trust circles, and the bounded result is IdP malfunction rather than data disclosure.
