Technical Analysis
The openclaw-cli package had an exec environment policy denylist that missed several high-risk interpreter startup environment variables such as VIMINIT, EXINIT, LUA_INIT, and HOSTALIASES. This omission allowed these environment variables, if supplied by an operator, to override or influence downstream execution or network behavior, potentially leading to high impact on confidentiality, integrity, and availability. The vulnerability is tracked as CVE-2026-43584 with a CVSS 3.1 score of 8.8 (high severity). The fix involved expanding the denylist to include these variables and was released in version 2026.4.10, with the latest patched npm release being 2026.4.14.
Potential Impact
The vulnerability allows operator-supplied environment variables related to interpreter startup to bypass the security denylist, potentially influencing downstream execution or network behavior. This can lead to high impact on confidentiality, integrity, and availability of the system running openclaw-cli versions before 2026.4.10.
Mitigation Recommendations
Users should upgrade openclaw-cli to version 2026.4.10 or later. The latest npm release 2026.4.14 includes the fix. Applying this update mitigates the vulnerability by expanding the exec environment denylist to cover the high-risk interpreter startup variables.
