Machine-written summary

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

OpenAM openam-federation versions before 16.1.1 are affected. An attacker who can get a logged-in user to visit a crafted URL can receive that user's raw session token, which may allow session hijacking; the source notes that exploitation depends on a non-default configuration with the Cross-Domain Single Sign-On servlet enabled. Upgrade to version 16.1.1.
