CVE-2022-47318Network attack vector

Arbitrary Ruby code execution via filename eval

Published Jan 17, 2023 · Updated Apr 4, 2025

Code injection in Ruby/Git before 1.13.0 allows remote authenticated users to execute arbitrary Ruby code through a crafted filename. Git::Lib#ls_files passes quoted filenames returned by git ls-files to Ruby eval while attempting to unescape them, treating filename content as code. Execution requires a user to load the attacker-controlled repository and invoke the affected file-listing path, after which code runs with that user's privileges.
