PHP_CodeSniffer gitblame report command injection via crafted filename

CVE-2026-67434 / GHSA-hmqg-cxww-wqhq

More information

Details

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.

Many thanks to both @​Faze-up and @​edorian for responsibly disclosing this vulnerability.

Fixed

• SECURITY FIX: 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. #​1473
  • Users using the default Full report, or any of the other non-*blame reports, are not affected.
  • For more details, see the security advisory.
  • Thanks go to Faze-up and Volker Dusch for responsibly disclosing the vulnerability.
  • Additionally, thanks go to Volker Dusch, Rodrigo Primo, Dan Wallis and Juliette Reinders Folmer for creating and testing the fix.
• Fixed bug #​1320: Generic.Strings.UnnecessaryHeredoc: the fixer could incidentally change tab indentation to space indentation in select lines in the heredoc body.
• Fixed bug #​1354: PSR12.Functions.ReturnTypeDeclaration: prevent an "Undefined array key" warning if the code under scan contains a parse error.
  • Thanks to Dan Wallis for the patch.
• Fixed bug #​1357: Squiz.Scope.StaticThisUsage: false positive for usage of $this in non-static closures nested in OO methods.
• Fixed bug #​1368: PEAR.Functions.FunctionDeclaration: the indentation for subsequent lines in multi-line block comments within a multi-line function signature, would be incorrectly determined, leading to false positives and resulting in a fixer conflict when running phpcbf.
  • This also fixes, by extension, the same issue in the Squiz.Functions.MultiLineFunctionDeclaration sniff.
• Fixed bug #​1418: Tokenizer/PHP: tokenization of an inline else colon after an inline comment could fail and/or throw a "Trying to access array offset on null" warning.
  • Thanks to Lazizbek Ergashev for the patch.
• Fixed bug #​1435: Generic.Formatting.MultipleStatementAlignment would get into a fixer conflict for multiple assignments within a single statement spanning multiple lines.
  • Same as when the statement would be single-line, alignment of subsequent assignment operators within the same multi-line statement will now be ignored.
  • Thanks to Sergei Morozov for the patch.
• Fixed bug #​1451: Tokenizer/PHP: prevent an "Undefined array key" warning during live coding when a file ends on the name in a constant declaration.
  • Thanks to Lazizbek Ergashev and Sai Asish Y for the patch.

  • Thanks to Rodrigo Primo for the patch.
