CVE-2026-62213Network attack vectorHinoki check available

Token disclosure via untrusted outbound service URLs

Published Jul 17, 2026 · Updated Oct 8, 2026

Token leakage in @openclaw/msteams before 2026.5.27 allows remote authenticated users to obtain Bot Framework tokens via outbound requests. The Teams send/update/delete paths attach Bot Framework credentials to untrusted serviceUrl hosts without validating the destination trust boundary. Exploitation requires the integration to be enabled and lower-trust input to reach those paths; the documented consequence is credential disclosure, not code execution.
