How to Fix GHSA-3q5q-f79q-7hr2

To remediate this vulnerability, upgrade all affected Rubyzip dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

rubyzip fixed: 1.2.1 
Upgrade rubyzip to 1.2.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for rubyzip

How to Check if You Are Affected

To determine whether your application is affected by GHSA-3q5q-f79q-7hr2, inspect your project dependencies for Rubyzip:

inspect dependencies for rubyzip

Analyze the terminal output to locate any version of Rubyzip in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Rubyzip, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Withdrawn, accidental duplicate publish. The Zip::File component in the rubyzip gem before 1.2.1 for Ruby has a directory traversal vulnerability. If a site allows uploading of .zip files, an attacker can upload a malicious file that uses "../" pathname substrings to write arbitrary files to the filesystem.
