CVE-2026-56692
NanoClaw < 2.1.17 - Arbitrary File Read via Symlink Following in forwardAttachedFiles
Description
NanoClaw before 2.1.17 contains a symlink following vulnerability in forwardAttachedFiles that allows container-controlled agents to exfiltrate host-readable files. The host validates attachment filenames using only isSafeAttachmentName before copying with fs.copyFileSync, which follows symlinks without containment checks, allowing malicious agents to disclose arbitrary host files.
