Arbitrary file write via unsanitized archive paths
Published Nov 7, 2025 · Updated Nov 7, 2025
Path traversal in Jared Allard archives before 1.0.1 allows attackers to write files outside the target directory via a crafted archive. The extract function joins each untrusted archive-header name to the destination and creates the resulting path without first verifying that it remains beneath that destination. The importing program must accept an attacker-controlled archive; resulting file writes inherit its process permissions and enable code execution when executable or configuration paths are overwritten.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
