Lifecycle Timeline
4DescriptionCVE.org
OpenClaw versions prior to 2026.2.23 contain an exec approval bypass vulnerability in allowlist mode where allow-always grants could be circumvented through unrecognized multiplexer shell wrappers like busybox and toybox sh -c commands. Attackers can exploit this by invoking arbitrary payloads under the same multiplexer wrapper to satisfy stored allowlist rules, bypassing intended execution restrictions.
AnalysisAI
OpenClaw contains an execution approval bypass vulnerability in allowlist mode that allows authenticated attackers to circumvent allow-always grants through unrecognized multiplexer shell wrappers like busybox and toybox. Attackers with low-level privileges can invoke arbitrary payloads under these multiplexer wrappers to satisfy stored allowlist rules while executing unintended commands. This affects all OpenClaw versions prior to 2026.2.23, with a patch now available from the vendor.
Technical ContextAI
OpenClaw (CPE: cpe:2.3:a:openclaw:openclaw) appears to be an execution control or command approval system that implements allowlist-based security controls. The vulnerability is rooted in CWE-184 (Incomplete List of Disallowed Inputs), where the allowlist validation logic fails to recognize and properly handle multiplexer shell wrappers such as busybox and toybox when processing 'sh -c' command invocations. These lightweight, multi-call binary implementations bundle multiple Unix utilities into a single executable and are commonly used in embedded systems and containers. The flaw allows attackers to wrap malicious payloads in these unrecognized shell wrappers, causing the allowlist engine to match against the wrapper itself rather than the actual payload being executed, thereby bypassing the intended security restrictions.
RemediationAI
Upgrade OpenClaw to version 2026.2.23 or later to fully remediate this vulnerability. The vendor has released a patch available at https://github.com/openclaw/openclaw/commit/a67689a7e3ad494b6637c76235a664322d526f9e which addresses the multiplexer shell wrapper bypass issue. Review the official security advisory at https://github.com/openclaw/openclaw/security/advisories/GHSA-gwqp-86q6-w47g for complete upgrade instructions and any additional configuration changes. As an interim mitigation if immediate patching is not possible, review and audit all allowlist rules to explicitly deny or restrict busybox and toybox shell wrapper invocations, implement additional command validation layers, and restrict network access to OpenClaw services to trusted IP ranges only. Monitor execution logs for suspicious 'sh -c' command patterns involving multiplexer binaries.
