ecosystem impact- 3 npm packages depend on openclaw (3 direct, 0 indirect)
Ecosystem-wide dependent count for version 2026.3.24.
DescriptionCVE.org
OpenClaw before 2026.3.24 contains an arbitrary code execution vulnerability in local plugin and hook installation that allows attackers to execute malicious code by crafting a .npmrc file with a git executable override. During npm install execution in the staged package directory, attackers can leverage git dependencies to trigger execution of arbitrary programs specified in the attacker-controlled .npmrc configuration file.
AnalysisAI
Arbitrary code execution in OpenClaw versions prior to 2026.3.24 enables local attackers to execute malicious code during npm package installation by crafting a malicious .npmrc file that overrides the git executable. When npm install runs in the staged package directory with git dependencies, the attacker-controlled .npmrc configuration triggers execution of arbitrary programs specified by the attacker. Exploitation requires user interaction to install the malicious plugin or hook locally. No public exploit identified at time of analysis.
Technical ContextAI
CWE-349 (Acceptance of Extraneous Untrusted Data With Trusted Data) vulnerability exploits npm's configuration hierarchy during local plugin installation. Attacker-supplied .npmrc files in staged directories override git executable paths, enabling arbitrary command execution when npm resolves git-based dependencies. The vulnerability stems from insufficient validation of configuration files within untrusted package contexts during the installation workflow.
RemediationAI
Vendor-released patch: upgrade to OpenClaw version 2026.3.24 or later, which addresses the arbitrary code execution vulnerability in npm configuration handling. Until patching is feasible, implement strict controls on plugin and hook installation sources: only install from verified, trusted repositories and avoid installing plugins from untrusted or third-party sources. Conduct manual inspection of package contents, specifically .npmrc files, before local installation. Disable or restrict local plugin installation functionality if not operationally required.
