CVE-2026-34509 Details
Description
Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
A sender allowlist bypass vulnerability has been identified in the OpenClaw Microsoft Teams plugin, affecting versions prior to 2026.3.8. This vulnerability allows unauthorized senders to circumvent authorization checks. When a team or channel route allowlist is set with an empty groupAllowFrom parameter, the message handler automatically grants wildcard sender authorization. This enables any sender in the corresponding team or channel to initiate replies in allowlisted Teams routes, thereby exploiting the authorization mechanism.
Users can update to OpenClaw version 2026.3.8 or later, where this vulnerability has been patched.
