CVSS 7.3 · HIGH

CVE-2026-43531

OpenClaw before 2026.4.9 contains an environment variable injection vulnerability allowing malicious workspace .env files to set runtime-control variables. Attackers can inject variables affecting update sources, gateway URLs, ClawHub resolution, and browser executable paths to compromise application behavior.

Analysis

OpenClaw is a niche workspace management tool with limited adoption in the general web and mobile development stack. While the vulnerability allows for environment variable injection and potentially critical behavior changes via malicious workspace files, the software's narrow user base does not warrant a priority alert for the broader community.

Actively exploited

KEV (Known Exploited Vulnerabilities) is CISA's catalog of CVEs confirmed as actively exploited in the real world. If a CVE is on KEV, someone is already using it in attacks.

CVSS 10.0

CVSS 10.0 — máxima severidad teórica. Explotable de forma remota, sin privilegios, con impacto total. Aún no confirmada como explotada en el mundo real, pero parchea ya.
