CVE-2026-22171: Improper Limitation of a Pathname to a Restricted Directory

OpenClaw versions prior to 2026.2.19 contain a path traversal vulnerability in the Feishu media download flow where untrusted media keys are interpolated directly into temporary file paths in extensions/feishu/src/media.ts. An attacker who can control Feishu media key values returned to the clien...

CVE-2026-22178: Inefficient Regular Expression Complexity

OpenClaw versions prior to 2026.2.19 construct RegExp objects directly from unescaped Feishu mention metadata in the stripBotMention function, allowing regex injection and denial of service. Attackers can craft nested-quantifier patterns or metacharacters in mention metadata to trigger catastroph...

OpenClaw: Feishu webhook mode accepted forged events when only `verificationToken` was configured

Summary Feishu webhook mode allowed deployments that configured only verificationToken without encryptKey. In that state, forged inbound events could be accepted because the weaker configuration did not provide the required cryptographic verification boundary. Impact An unauthenticated network...

GHSA-M69H-JM2F-2PV8 OpenClaw: Feishu reaction events could bypass group authorization and mention gating

Summary A Feishu reaction-originated synthetic event could misclassify a group conversation as p2p when the inbound reaction payload omitted chattype. Authorization and mention-gating logic keyed off that incorrect chat type and evaluated the event as a direct message instead of a group message...
