Detailsinfo

A vulnerability classified as critical has been found in OpenClaw up to 2026.3.30. This affects some unknown processing of the component Environment Variable Handler. The manipulation of the argument PIP_INDEX_URL/UV_INDEX_URL with an unknown input leads to a incomplete blacklist vulnerability. CWE is classifying the issue as CWE-184. The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete, leading to resultant weaknesses. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

OpenClaw before 2026.3.31 fails to properly sanitize PIP_INDEX_URL and UV_INDEX_URL environment variables in host execution contexts, allowing attackers to redirect Python package-index traffic. Attackers can exploit this bypass to intercept or manipulate package management operations by injecting malicious index URLs through unsanitized environment variables.

The weakness was shared by KeenSecurityLab and qclawer as GHSA-7ggg-pvrf-458v. The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-41391 since 04/20/2026. The exploitability is told to be difficult. An attack has to be approached locally. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1562.006 for this issue.
