Summary
OpenClaw 2026.6.9 before 2026.8.1 Cross-Context Policy Bypass via Feishu unpin
Details

OpenClaw versions >= 2026.6.9 and < 2026.8.1 do not declare the native chatId parameter as a delivery target in the Feishu unpin feature, so unpin requests can bypass the shared same-provider cross-context target check. When tools.message.crossContext.allowWithinProvider is disabled, an admitted (authenticated) sender can remove a pin from another Feishu group that the sender and the configured account are otherwise permitted to access, bypassing the intended cross-context message mutation policy. Feishu membership and group authorization still apply, and the demonstrated impact is limited to message mutation (pin removal). The issue is fixed in 2026.8.1.
