Impact
PHPUnit forwards PHP INI settings to child processes (used for isolated/PHPT test execution) as
-d name=valuecommand-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. Settingauto_prepend_fileto an attacker-controlled path yields remote code execution in the child process.Sources of INI values that participate in the attack:
<ini name="…" value="…"/>entries inphpunit.xml/phpunit.xml.distini_get_all()Threat Model
Exploitation requires the attacker to control the content of an INI value read by PHPUnit. In practice this means write access to the project's
phpunit.xml, the hostphp.ini, or the PHP binary's environment. The most realistic exposure is Poisoned Pipeline Execution (PPE): a pull request from an untrusted contributor that modifiesphpunit.xmlto include a newline-containing INI value, executed by a CI system that runs PHPUnit against the PR without isolation. A malicious newline is not visibly distinguishable from a legitimate value in a typical diff review.Affected component
PHPUnit\Util\PHP\JobRunner::settingsToParameters().Patches
The fix has two parts:
1. Reject line-break characters
Because a newline or carriage return in an INI value has no legitimate use and is the primitive that enables directive injection, any PHP setting value containing
\nor\ris now rejected with an explicitPhpProcessException. This follows the same "visibility over silence" principle applied in CVE-2026-24765: the anomalous state fails loudly in CI output rather than being silently sanitized, giving operators an opportunity to investigate whether it reflects tampering, environment contamination, or an unexpected upstream change.2. Quote remaining metacharacters
Values containing
"or;, both of which have legitimate uses (e.g., regex-valued INI settings such asddtrace'sdatadog.appsec.obfuscation_parameter_value_regexp), are wrapped in double quotes with inner"escaped as\", so PHP's INI parser reads them as literal string contents rather than comment/delimiter tokens. Plain values are forwarded unchanged so that boolean keywords (On/Off) and bitwise expressions (E_ALL & ~E_NOTICE) retain their INI semantics.Workarounds
If upgrading is not immediately possible:
<ini value="…">entry inphpunit.xml/phpunit.xml.distcontains newline,", or;characters, and that nothing writes such values into configuration at build time.pull_request_targetand similar). These mitigations apply to the broader PPE risk class and are effective against this vulnerability as well.phpunit.xml: Treatphpunit.xmlas security-sensitive in code review, particularly<ini>entries.php.inidoes not contain values with embedded newlines or unescaped metacharacters.References
