CVE-2026-35654Network attack vector

Unauthorized feedback recording via unchecked Teams invokes

Published Apr 10, 2026 · Updated Apr 10, 2026

Authorization bypass in OpenClaw before 2026.3.25 allows remote attackers to record Microsoft Teams session feedback via feedback invokes. The Microsoft Teams feedback-invoke path accepted message/submitAction feedback without applying the DM and group sender-authorization checks used for messages. Reachability requires an enabled Microsoft Teams channel and a crafted invoke from a sender excluded by the configured DM or group policy; the impact is limited to feedback recording or reflection.
