The record
HKUDS OpenHarness prior to PR #159 remediation contains a session key derivation vulnerability that allows authenticated participants in shared chats or threads to hijack other users' sessions by exploiting a shared ohmo session key that lacks sender identity verification. Attackers can reuse another user's conversation state and replace or interrupt their active tasks by colliding into the same session boundary through the shared chat or thread scope.
