Openclaw: >> Openclaw >> 2026.3.22 Security Vulnerabilities
OpenClaw before 2026.3.25 contains a missing rate limiting vulnerability in Telegram webhook authentication that allows attackers to brute-force weak webhook secrets. The vulnerability enables repeated authentication guesses without throttling, permitting attackers to systematically guess webhook secrets through brute-force attacks.

OpenClaw before 2026.3.25 contains a server-side request forgery vulnerability in multiple channel extensions that fail to properly guard configured base URLs against SSRF attacks. Attackers can exploit unprotected fetch() calls against configured endpoints to rebind requests to blocked internal destinations and access restricted resources.

OpenClaw before 2026.3.23 contains a replay identity vulnerability in Plivo V2 signature verification that allows attackers to bypass replay protection by modifying query parameters. The verification path derives replay keys from the full URL including query strings instead of the canonicalized base URL, enabling attackers to mint new verified request keys through unsigned query-only changes to signed requests.

OpenClaw before 2026.3.25 contains a privilege escalation vulnerability where silent local shared-auth reconnects auto-approve scope-upgrade requests, widening paired device permissions from operator.read to operator.admin. Attackers can exploit this by triggering local reconnection to silently escalate privileges and achieve remote code execution on the node.

OpenClaw before 2026.3.25 contains an improper access control vulnerability in the HTTP /sessions/:sessionKey/kill route that allows any bearer-authenticated user to invoke admin-level session termination functions without proper scope validation. Attackers can exploit this by sending authenticated requests to kill arbitrary subagent sessions via the killSubagentRunAdmin function, bypassing ownership and operator scope restrictions.

OpenClaw before 2026.3.31 (patched in 2026.4.8) contains a request body replay vulnerability in fetchWithSsrFGuard that allows unsafe request bodies to be resent across cross-origin redirects. Attackers can exploit this by triggering redirects to exfiltrate sensitive request data or headers to unintended origins.

OpenClaw before 2026.4.2 reuses the PKCE verifier as the OAuth state parameter in the Gemini OAuth flow, exposing it through the redirect URL. Attackers who capture the redirect URL can obtain both the authorization code and PKCE verifier, defeating PKCE protection and enabling token redemption.

OpenClaw versions prior to commit 8aceaf5 contain a preflight validation bypass vulnerability in shell-bleed protection that allows attackers to execute blocked script content by using piped or complex command forms that the parser fails to recognize. Attackers can craft commands such as piped execution, command substitution, or subshell invocation to bypass the validateScriptFileForShellBleed() validation checks and execute arbitrary script content that would otherwise be blocked.
