OpenClaw before 2026.3.28 contains a missing rate limiting vulnerability in the Nextcloud Talk webhook authentication that allows attackers to brute-force weak shared secrets. Attackers who can reach the webhook endpoint can exploit this to forge inbound webhook events by repeatedly attempting authentication without throttling.
OpenClaw before 2026.3.24 contains a sandbox bypass vulnerability in the message tool that allows attackers to read arbitrary local files by using mediaUrl and fileUrl alias parameters that bypass localRoots validation. Remote attackers can exploit this by routing file requests through unvalidated alias parameters to access files outside the intended sandbox directory.
OpenClaw before 2026.3.28 downloads and stores inbound media from Zalo channels before validating sender authorization. Unauthorized senders can force network fetches and disk writes to the media store by sending messages that are subsequently rejected.
OpenClaw before 2026.3.28 contains an insufficient scope validation vulnerability in the node pairing approval path that allows low-privilege operators to approve nodes with broader scopes. Attackers can exploit missing callerScopes validation in node-pairing.ts to extend privileges onto paired nodes beyond their authorization level.
OpenClaw before 2026.3.28 contains a sender policy bypass vulnerability in the Google Chat and Zalouser extensions where route-level group allowlist policies silently downgrade to open policy. Attackers can exploit this policy resolution flaw to bypass sender restrictions and interact with bots despite configured allowlist restrictions.
OpenClaw before 2026.3.28 contains a privilege escalation vulnerability in the /pair approve command path that fails to forward caller scopes into the core approval check. A caller with pairing privileges but without admin privileges can approve pending device requests asking for broader scopes including admin access by exploiting the missing scope validation in extensions/device-pair/index.ts and src/infra/device-pairing.ts.
OpenClaw through 2026.3.23 (fixed in commit 4797bbc) contains a path traversal vulnerability in media parsing that allows attackers to read arbitrary files by bypassing path validation in the isLikelyLocalPath() and isValidMedia() functions. Attackers can exploit incomplete validation and the allowBareFilename bypass to reference files outside the intended application sandbox, resulting in disclosure of sensitive information including system files, environment files, and SSH keys.
