CVE-2026-41391 PUBLISHED

OpenClaw < 2026.3.31 - Environment Variable Bypass in Package Index URL Handling

Assigner: VulnCheck
Reserved: 20.04.2026 Published: 28.04.2026 Updated: 28.04.2026

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.
