OpenClaw before 2026.4.20 contains an improper environment variable validation vulnerability in MCP stdio server configuration that allows attackers to execute arbitrary code. Malicious workspace configurations can pass dangerous startup variables like NODE_OPTIONS, LD_PRELOAD, or BASH_ENV to spawned MCP server processes, enabling code injection when operators start sessions using those servers.
OpenClaw < 2026.4.22 - Authentication Bypass in Gateway Control UI Bootstrap Config Endpoint
OpenClaw before 2026.4.22 contains an authentication bypass vulnerability in the Control UI bootstrap config endpoint that allows unauthenticated attackers to read sensitive configuration fields. Attackers can access the bootstrap config route without a valid Gateway token to expose sensitive bootstrap and config information intended only for authenticated Control UI sessions.
OpenClaw < 2026.4.20 - Direct Message Misclassification in Feishu Card Actions
OpenClaw before 2026.4.20 contains a message classification vulnerability in Feishu card-action callbacks that misclassifies direct messages as group conversations. Attackers can bypass dmPolicy enforcement by triggering card-action flows in direct message conversations that should have been blocked by restrictive policies.
OpenClaw 2026.4.5 through 2026.4.19 - MiniMax API Host Override via Workspace dotenv
OpenClaw versions 2026.4.5 before 2026.4.20 contain an environment variable injection vulnerability allowing workspace dotenv to override MINIMAX_API_HOST. Attackers can redirect credentialed MiniMax API requests to attacker-controlled origins, exposing the MiniMax API key in Authorization headers.
OpenClaw < 2026.4.21 - Authorization Bypass in Owner-Enforced Commands via Wildcard Channel Senders
OpenClaw before 2026.4.21 contains an authorization bypass vulnerability in command-auth.ts that allows non-owner senders to execute owner-enforced slash commands when wildcard inbound senders are configured without explicit owner allowFrom settings. Attackers can exploit this by sending commands like /send, /config, or /debug on affected channels to bypass owner-only command authorization checks.
OpenClaw before 2026.4.22 derives loopback MCP owner context from spoofable server-issued bearer tokens in request headers. Non-owner loopback clients can present themselves as owner to bypass owner-gated operations by manipulating the sender-owner header metadata.
OpenClaw < 2026.4.20 - Server-Side Request Forgery in QQBot Direct Media Upload
OpenClaw before 2026.4.20 contains a server-side request forgery vulnerability in QQBot direct media upload that skips URL validation. Attackers can bypass SSRF protections by sending crafted image URLs to uploadC2CMedia and uploadGroupMedia endpoints to relay unintended requests.
OpenClaw before 2026.4.22 contains a server-side request forgery vulnerability in the Zalo plugin's sendPhoto function that fails to validate outbound photo URLs through the SSRF guard. Attackers can bypass SSRF protection by providing malicious photo URLs to the Zalo Bot API, enabling unauthorized access to internal resources.
OpenClaw < 2026.4.22 - Shell Expansion Bypass in Unquoted Heredocs via Exec Allowlist
OpenClaw before 2026.4.22 contains an exec allowlist analysis vulnerability allowing shell expansion hiding in unquoted heredoc bodies. Attackers can bypass allowlist validation by embedding shell expansion tokens in heredoc bodies to execute unapproved commands at runtime.
OpenClaw before 2026.4.20 fails to properly reserve the OPENCLAW_ runtime-control environment namespace in workspace dotenv files, allowing attackers to override critical runtime variables. Malicious workspaces can set variables like OPENCLAW_GIT_DIR to manipulate trusted OpenClaw runtime behavior during source-update or installer flows.
OpenClaw before 2026.4.22 contains a time-of-check/time-of-use race condition in the OpenShell filesystem bridge that allows attackers to read files outside the intended mount root. Attackers can exploit symlink swaps during filesystem operations to bypass sandbox restrictions and access unauthorized file contents.
OpenClaw before 2026.4.22 contains a time-of-check/time-of-use race condition in OpenShell sandbox filesystem writes that allows attackers to redirect writes outside the intended mount root. Attackers can exploit symlink swaps during filesystem operations to bypass sandbox restrictions and write files outside the local mount root.
OpenClaw before 2026.4.15 contains an arbitrary file read vulnerability in the QMD backend memory_get function that allows callers to read any Markdown files within the workspace root. Attackers with access to the memory tool can bypass path restrictions by providing arbitrary workspace Markdown paths to read files outside canonical memory locations or indexed QMD result sets.
OpenClaw < 2026.4.15 - Authentication Bypass in Feishu Webhook and Card-Action Validation
OpenClaw before 2026.4.15 contains an authentication bypass vulnerability in Feishu webhook and card-action validation that allows unauthenticated requests to reach command dispatch. Missing encryptKey configuration and blank callback tokens fail open instead of rejecting requests, enabling attackers to bypass signature verification and replay protection to execute arbitrary commands.
OpenClaw < 2026.4.15 - Bearer Token Validation Bypass via Stale SecretRef Resolution
OpenClaw before 2026.4.15 captures resolved bearer-auth configuration at startup, allowing revoked tokens to remain valid after SecretRef rotation. Gateway HTTP and WebSocket handlers fail to re-resolve authentication per-request, enabling attackers to use rotated-out bearer tokens for unauthorized gateway access.
OpenClaw before 2026.4.10 contains an insufficient environment variable denylist vulnerability in its exec environment policy that allows operator-supplied overrides of high-risk interpreter startup variables including VIMINIT, EXINIT, LUA_INIT, and HOSTALIASES. Attackers can exploit this by manipulating these environment variables to influence downstream execution behavior or network connectivity.
OpenClaw 2026.4.10 < 2026.4.14 - Loss of Group Tool-Policy Context in Delivery Queue Recovery
OpenClaw versions 2026.4.10 before 2026.4.14 fail to persist session context during delivery queue recovery for media replay. Attackers can exploit recovered queued outbound media to bypass group tool policy enforcement and weaken channel media restrictions after service restart or recovery.
OpenClaw < 2026.4.10 - DNS Rebinding SSRF via Hostname Validation Bypass
OpenClaw before 2026.4.10 contains a server-side request forgery vulnerability in browser navigation policy that allows attackers to bypass hostname validation through DNS rebinding attacks. Attackers can exploit inconsistent hostname resolution between validation and actual network requests to pivot to internal resources via unallowlisted hostname URLs.
OpenClaw before 2026.4.10 contains an improper network binding vulnerability in the sandbox browser CDP relay that exposes Chrome DevTools Protocol on 0.0.0.0. Attackers can access the DevTools protocol outside intended local sandbox boundaries by exploiting the overly broad binding configuration.
OpenClaw before 2026.4.10 contains an incomplete navigation guard vulnerability that allows attackers to trigger navigation without complete SSRF policy enforcement. Browser press/type style interactions, including pressKey and type submit flows, can bypass post-action security checks to execute unauthorized navigation.
