CVE-2026-111045

CLI Bridge: High-severity sandbox escape via dangling symlink

Published Oct 19, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
CLI Bridge provides filesystem access within a workspace root. Prior to 0.0.2, a dangling symlink pointing outside the workspace root bypasses resolveSafePath when fs.realpathSync throws ENOENT for a nonexistent target. The fallback resolves only the parent directory and returns the symlink path as safe, so write_file follows the link and can write arbitrary files outside the workspace root. This issue is fixed in version 0.0.2.
