DescriptionCVE.org

OpenClaw before 2026.3.22 contains an allowlist bypass vulnerability in system.run approvals that fails to unwrap /usr/bin/time wrappers. Attackers can bypass executable binding restrictions by using an unregistered time wrapper to reuse approval state for inner commands.

AnalysisAI

Allowlist bypass in OpenClaw before 2026.3.22 permits authenticated attackers to execute arbitrary commands by wrapping disallowed executables with /usr/bin/time. The vulnerability exploits incomplete validation in system.run approvals, which fail to detect time wrapper prefixes, allowing reuse of approval state for inner prohibited commands. Remote exploitation requires low-privilege authentication (PR:L) with network access, enabling full system compromise through command injection. No public exploit identified at time of analysis.

Technical ContextAI

CWE-706 (Use of Incorrectly-Resolved Name or Reference) manifests in approval validation logic that parses command arguments without recursively inspecting wrapper utilities. The /usr/bin/time prefix obscures the true executable from allowlist checks, causing the approval framework to authorize the wrapper while executing the embedded disallowed binary with inherited permissions.

RemediationAI

Upgrade to OpenClaw version 2026.3.22 or later, which implements recursive wrapper detection in approval validation. Vendor-released patches address the allowlist bypass through commits 630f1479c44f78484dfa21bb407cbe6f171dac87 and 39409b6a6dd4239deea682e626bac9ba547bfb14, adding unwrap logic for time and similar dispatcher utilities. Organizations unable to upgrade immediately should restrict system.run approval grants to fully-qualified paths only, disable /usr/bin/time access in execution sandboxes, and audit existing approval configurations for wrapper-prefixed commands.
