Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

OpenAM (Maven package org.openidentityplatform.openam:openam-radius) versions before 16.1.1 are affected. An unauthenticated network attacker can send forged RADIUS Access-Accept responses that the client accepts without checking them, obtaining an OpenAM session for any RADIUS username without the shared secret. Upgrade to version 16.1.1, which fixes the issue.

Written 2 Nov 2026.
