PHP_CodeSniffer tokenizes PHP files and detects violations of a defined set of coding standards. Prior to versions 3.13.6 and 4.0.2, PHP_CodeSniffer contains a command injection vulnerability in the code that generates the Gitblame, Hgblame, and Svnblame report formats. As a result, running PHP_CodeSniffer over untrusted files, for example in a continuous integration pipeline that scans pull requests, or on a developer machine reviewing third party code, could result in attacker controlled shell commands being executed when the Gitblame, Hgblame, or Svnblame report processes a file whose name contains shell metacharacters. Users using the default Full report, or any of the other non-blame reports, are not affected. Users on a runtime platform which does not allow filenames to contain shell metacharacters, such as " and ;, are not affected. This issue is fixed in versions 3.13.6 and 4.0.2.

### Impact PHP_CodeSniffer versions before v3.13.6 and v4.0.2 contain a command injection vulnerability in the code creating the `Gitblame`, `Hgblame` and `Svnblame` report(s). As a result, running PHP_CodeSniffer over untrusted files, for example, in a CI pipeline that scans pull requests, or on a developer machine reviewing third-party code, could result in attacker-controlled shell commands being executed when the `Gitblame`, `Hgblame` or `Svnblame` report(s) would process a file whose name contains shell metacharacters. * Users using the default `Full` report, or any of the other non-*blame reports, are not affected. * Users on a runtime platform which does not allow filenames to contain shell metacharacters, such as `"` and `;`, are not affected. ### Patched versions The issue has been fixed in PHP_CodeSniffer v3.13.6 and v4.0.2. We recommend all users upgrade to these versions at their earliest convenience. ### Workaround Users of PHP_CodeSniffer who cannot upgrade immediately should ensure they do not use the `Gitblame`, `Hgblame` or the `Svnblame` reports when scanning untrusted code. This is especially relevant for CI jobs, pre-commit or review tooling, automated review services, and any service that scans untrusted repositories or uploaded source trees. ### Credits Many thanks to both [@Faze-up](https://github.com/Faze-up) and [@edorian](https://github.com/edorian) for responsibly disclosing this vulnerability. ### How can I report a security bug? Please report security vulnerabilities privately via [the "Security and quality" tab on the PHP_CodeSniffer repository](https://github.com/PHPCSStandards/PHP_CodeSniffer/security).
