CVE-2026-56876

Exploit

extract-zip unvalidated symlink path traversal

extract-zip does not validate symlink targets when extracting zip archives. When processing a malicious zip file containing a symlink with a relative path like '../../../../etc/passwd', extract-zip will extract the symlink without validation, allowing it to point outside the extraction directory. Depending on how extract-zip is used, an attacker could read or write to arbitrary files.

CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

CWE-61 UNIX Symbolic Link (Symlink) Following

The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.
