CVE-2026-29064Public exploit

Arbitrary file read or write via symlink escape

Published Mar 6, 2026 · Updated Mar 6, 2026

Path traversal in Zarf 0.54.0 through 0.73.0 allows context-dependent attackers to read or write arbitrary host files via a crafted package. The defaultHandler, stripHandler, and filterHandler functions create archive-entry symlinks without verifying that their targets resolve within the extraction destination. Processing an untrusted package or generic archive is required; resulting symlinks permit out-of-directory file reads or overwrites but do not create an execution path by themselves.
