Openclaw: >> Openclaw >> 2026.2.21 Security Vulnerabilities
OpenClaw versions prior to 2026.2.23 contain an html injection vulnerability in the HTML session exporter that allows attackers to execute arbitrary javascript by injecting malicious mimeType values in image content blocks. Attackers can craft session entries with specially crafted mimeType attributes that break out of the img src data-URL context to achieve cross-site scripting when exported HTML is opened.

OpenClaw versions prior to 2026.3.1 fail to properly handle authentication bootstrap errors during startup, allowing browser-control routes to remain accessible without authentication. Local processes or loopback-reachable SSRF paths can exploit this to access browser-control routes including evaluate-capable actions without valid credentials.

OpenClaw versions prior to 2026.3.2 fail to pass the senderIsOwner flag when processing Discord voice transcripts in agentCommand, causing the flag to default to true. Non-owner voice participants can exploit this omission to access owner-only tools including gateway and cron functionality in mixed-trust channels.

OpenClaw before 2026.2.24 contains a sandbox network isolation bypass vulnerability that allows trusted operators to join another container's network namespace. Attackers can configure the docker.network parameter with container:<id> values to reach services in target container namespaces and bypass network hardening controls.

OpenClaw versions prior to 2026.2.26 server-http contains an authentication bypass vulnerability in gateway authentication for plugin channel endpoints due to path canonicalization mismatch between the gateway guard and plugin handler routing. Attackers can bypass authentication by sending requests with alternative path encodings to access protected plugin channel APIs without proper gateway authentication.

OpenClaw versions prior to 2026.2.22 contain an arbitrary shell execution vulnerability in shell environment fallback that trusts the unvalidated SHELL path from the host environment. An attacker with local environment access can inject a malicious SHELL variable to execute arbitrary commands with the privileges of the OpenClaw process.

OpenClaw versions prior to 2026.2.24 contain a path traversal vulnerability where @-prefixed absolute paths bypass workspace-only file-system boundary validation due to canonicalization mismatch. Attackers can exploit this by crafting @-prefixed paths like @/etc/passwd to read files outside the intended workspace boundary when tools.fs.workspaceOnly is enabled.

OpenClaw versions prior to 2026.2.25 contain an authentication hardening gap in browser-origin WebSocket clients that allows attackers to bypass origin checks and auth throttling on loopback deployments. An attacker can trick a user into opening a malicious webpage and perform password brute-force attacks against the gateway to establish an authenticated operator session and invoke control-plane methods.

OpenClaw versions prior to 2026.2.24 contain an improper path validation vulnerability in sandbox media handling that allows absolute paths under the host temporary directory outside the active sandbox root. Attackers can exploit this by providing malicious media references to read and exfiltrate arbitrary files from the host temporary directory through attachment delivery mechanisms.
