In versions 12.5.21 and 13.1.5, PHPUnit forwards PHP INI settings to child processes (used for isolated/PHPT test execution) as -d name=value command-line arguments without neutralizing INI metacharacters. Because PHP's INI parser interprets \" as a string delimiter, ; as the start of a comment, and most importantly a newline as a directive separator, a value containing a newline is parsed by the child process as multiple INI directives. An attacker able to influence a single INI value can therefore inject arbitrary additional directives into the child's configuration, including auto_prepend_file, extension, disable_functions, open_basedir, and others. Setting auto_prepend_file to an attacker-controlled path yields remote code execution in the child process. This issue has been patched in versions 12.5.22 and 13.1.6."}], "lastModified": "2026-05-08T19:45:25.910", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:phpunit_project:phpunit:12.5.21:*:*:*:*:-:*:*", "vulnerable": true, "matchCriteriaId": "14399E6E-3DD0-4CD6-8D89-8C5A99034AE6"}, {"criteria": "cpe:2.3:a:phpunit_project:phpunit:13.1.5:*:*:*:*:-:*:*", "vulnerable": true, "matchCriteriaId": "7948E33A-A79E-405B-AE5A-3CB710478DB9"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
