CVSS 8.1 · HIGH

CVE-2026-41364

OpenClaw before 2026.3.31 contains a symlink following vulnerability in SSH sandbox tar upload that allows remote attackers to write arbitrary files. Attackers can exploit this by uploading tar archives containing symlinks to escape the sandbox and overwrite files on the remote host.

Analysis

OpenClaw is a niche open-source game engine recreation. While an arbitrary file write via symlink follow is a high-severity bug, the product is not used in professional software development, cloud infrastructure, or common consumer environments, making it irrelevant to the target audience.

How to read this card

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.
