OpenClaw Credential Exposure via Workspace Dotenv Override

Mitigation Strategies

To mitigate the vulnerability in OpenClaw prior to version 2026.5.28, you should upgrade to OpenClaw version 2026.5.28 or later.

• Restrict the affected workspace dotenv feature to trusted operators only.
• Disable the affected feature when it is not needed.
• Apply general hardening practices such as keeping channel and tool allowlists narrow.
• Avoid sharing Gateways between untrusted users.

Executive Summary

CVE-2026-59261 is a credential exposure vulnerability in OpenClaw versions prior to 2026.5.28. It occurs because workspace dotenv files can override provider credentials. This means that attackers who have lower-trust access to certain configured input paths can manipulate these dotenv files to expose sensitive data and credentials that should normally remain protected within trusted boundaries.

Impact Analysis

This vulnerability can lead to the exposure of sensitive information and credentials, which can compromise the confidentiality and integrity of your system. Attackers with local access and low privileges, but with user interaction, can exploit this flaw to gain unauthorized access to credentials. This could allow them to impersonate trusted providers or access restricted resources, potentially leading to further security breaches.

Compliance Impact

The vulnerability in OpenClaw allows attackers with lower-trust access to expose sensitive data and credentials that should remain within trusted boundaries. This exposure of sensitive information could potentially lead to non-compliance with standards and regulations such as GDPR and HIPAA, which require protection of sensitive data and credentials.

However, the provided information does not explicitly mention specific impacts on compliance with these regulations or standards. It emphasizes the risk of sensitive data exposure and recommends mitigation steps such as upgrading to a patched version, restricting feature access to trusted operators, and disabling the vulnerable feature when not needed.

Detection Guidance

This vulnerability involves workspace dotenv files overriding provider credentials in OpenClaw versions prior to 2026.5.28. Detection involves identifying if your OpenClaw installation is an affected version and if the vulnerable feature related to workspace dotenv files is enabled and accessible.

Since the attack vector is local and requires access to configured input paths, detection can include checking for the presence of workspace dotenv files in those paths and verifying if they contain credential overrides.

Suggested commands to help detect potential exploitation or presence of this vulnerability might include:

• Check OpenClaw version installed: `openclaw --version` or equivalent command to verify if the version is prior to 2026.5.28.
• Search for workspace dotenv files in configured input paths, for example: `find /path/to/openclaw/workspace -name '*.env'`.
• Inspect dotenv files for suspicious credential overrides: `grep -i 'CREDENTIAL' /path/to/openclaw/workspace/*.env` or similar patterns.
• Audit file access logs or system logs for unauthorized or unexpected access to these dotenv files.

Note that no specific detection commands are provided in the resources, so these suggestions are based on the nature of the vulnerability and typical investigative steps.
