CVE-2026-28457

medium

Description

OpenClaw versions prior to 2026.2.14 contain a path traversal vulnerability in sandbox skill mirroring (must be enabled) that uses the skill frontmatter name parameter unsanitized when copying skills into the sandbox workspace. Attackers who provide a crafted skill package with traversal sequences like ../ or absolute paths in the name field can write files outside the sandbox workspace root directory.
