CVE-2026-41570— PHPUnit: Argument injection via newline in PHP INI values forwarded to child processes

PHPUnit: Argument injection via newline in PHP INI values forwarded to child processes

PHPUnit is a testing framework for PHP. 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.

对CRLF序列的转义处理不恰当(CRLF注入)

PHPUnit 参数注入漏洞

PHPUnit是Sebastian Bergmann个人开发者的一个PHP单元测试框架。 PHPUnit 12.5.21版本和13.1.5版本存在参数注入漏洞，该漏洞源于将PHP INI设置转发给子进程时未中和INI元字符，可能导致远程代码执行。
