CVE-2026-6729

Description

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.
