Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

OpenClaw 版本 >= 2026.6.9 且 < 2026.8.1 中，在未取消置顶（unpin）功能中未将原生 chatId 参数声明为投递目标，导致未取消置顶请求可以绕过共享同一提供方的跨上下文目标检查。当 tools.message.crossContext.allowWithinProvider 配置项被禁用时，经过身份验证（已认证）的用户可以取消对其与配置账户均有权限访问的飞书群组的某条消息的置顶状态，从而绕过了预期的跨上下文消息修改策略。飞书的成员资格和群组授权机制仍然有效，因此该问题的实际影响仅

OpenClaw 2026.6.9 before 2026.8.1 Cross-Context Policy Bypass via Feishu unpin
Source: CVE Program / CVE List V5
Vulnerability Description
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.
