Vulnerability in zip (CVE-2025-29787)
Summary
Vulnerability in zip (CVE-2025-29787). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 2.3.0 or later.
Original description
The description as published by the source.
zip is a zip library for rust which supports reading and writing of simple ZIP files. In the archive extraction routine of affected versions of the zip crate starting with version 1.3.0 and prior to version 2.3.0, symbolic links earlier in the archive are allowed to be used for later files in the archive without validation of the final canonicalized path, allowing maliciously crafted archives to overwrite arbitrary files in the file system when extracted. Users who extract untrusted archive files using the following high-level API method may be affected and critical files on the system may be overwritten with arbitrary file permissions, which can potentially lead to code execution. Version 2.3.0 fixes the issue.
