Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-377: Insecure Temporary File, where creating and using insecure temporary files can leave application and system data vulnerable to attack. In Ruby parser, 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

The `diff_pp` function in `lib/gauntlet_rubyparser.rb` in the ruby_parser gem 3.1.1 and earlier for Ruby allows local users to overwrite arbitrary files via a symlink attack on a temporary file with a predictable name in `/tmp`.
