CVE-2026-53813: OpenClaw Path Traversal in Memory-Core Artifact Loading

Technical summary

CVE-2026-53813 is a path traversal vulnerability in OpenClaw's memory-core artifact loading mechanism. The vulnerability arises from insufficient validation of artifact paths when workspace state influences local package root resolution. An attacker with workspace-level access can manipulate path inputs to load memory-core artifacts from unintended directories, bypassing intended containment controls. The vulnerability is classified under CWE-427 (Untrusted Search Path), indicating the root cause involves improper handling of search paths for loading executable or security-sensitive components.

Business impact

Organizations using OpenClaw prior to version 2026.4.25 face the risk of code execution and data exfiltration within their development or build environments. An insider or threat actor with workspace access could leverage this to execute arbitrary commands, steal sensitive source code, credentials, or other intellectual property stored on the affected system. The impact extends beyond the compromised workspace, potentially affecting downstream systems that depend on artifacts generated by the vulnerable OpenClaw instance. This is particularly critical for organizations that use OpenClaw in CI/CD pipelines or for processing proprietary code.

Affected systems

OpenClaw versions prior to 2026.4.25 are affected. The vulnerability requires that an attacker have prior access to a workspace—either as a legitimate user, through compromised credentials, or via another access vector. Systems where OpenClaw runs with elevated privileges or processes sensitive data are at higher risk. Verify your installed OpenClaw version and assess which workspaces are accessible to external or untrusted users.

Exploitability

Exploitation requires local access and low privileges—an attacker must already have user-level permissions within an affected OpenClaw workspace. The attack requires no user interaction (UI:N) and can be executed straightforwardly once access is obtained (AC:L). No complex conditions or race conditions are necessary. However, the requirement for prior workspace access prevents opportunistic remote exploitation; this is an insider or post-compromise risk rather than a worm-like threat.

Remediation

Upgrade OpenClaw to version 2026.4.25 or later, which patches the artifact path resolution logic. Verify the patch through the vendor's security advisory and test in a non-production environment before deployment. As an interim control, restrict workspace access to only trusted users and monitor artifact loading activity for suspicious path patterns.

Patch guidance

Update OpenClaw to version 2026.4.25 or later according to the vendor's release notes and security advisory. If you cannot immediately upgrade, implement compensating controls: (1) restrict read and execute permissions on the workspace directory to authorized personnel only, (2) implement filesystem monitoring to detect artifact loading from unexpected paths, and (3) use SELinux or AppArmor profiles to confine OpenClaw's file access scope. Test the patch thoroughly in a development environment before applying to production systems.

Detection guidance

Monitor OpenClaw process creation and file access patterns, particularly for attempts to load artifacts from paths outside the expected workspace directories. Enable filesystem audit logging (auditd on Linux) to track open() and execve() syscalls initiated by OpenClaw, filtering for artifact filenames. Look for workspace state changes (configuration modifications) followed by artifact loading operations from unusual paths. Collect OpenClaw debug or verbose logs if available. SIEM rules should flag processes spawned by OpenClaw from unexpected parent processes or with unusual arguments. Note that this vulnerability requires authenticated workspace access, so focus detection on anomalous behavior by existing workspace users.

Why prioritize this

A CVSS score of 7.8 (HIGH) reflects the high impact (confidentiality, integrity, and availability all affected) despite the requirement for prior workspace access. This vulnerability should be prioritized because: (1) code execution is possible, allowing complete system compromise, (2) OpenClaw is likely used in sensitive development or build pipelines, (3) the fix is available and straightforward to deploy, and (4) the threat window remains open while older versions are in use. Organizations should treat this as a priority patch within 2–4 weeks, with accelerated timelines for systems handling critical intellectual property or running in multi-tenant environments.

Risk score, explained

The CVSS v3.1 score of 7.8 reflects CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. The Attack Vector (Local) and required Privileges (Low) prevent a higher score, but the lack of User Interaction required and high impact across all three CIA triad factors (confidentiality, integrity, availability) result in a HIGH severity rating. Organizations processing sensitive data or running OpenClaw in multi-user environments should consider this functionally equivalent to a critical patch; context-dependent risk may elevate it beyond the base CVSS score.
