Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

PHP_CodeSniffer versions before 3.13.6 and from 4.0.0 before 4.0.2 are vulnerable to command injection in the Gitblame, Hgblame and Svnblame reports. An attacker who can get PHP_CodeSniffer to scan a file whose name contains shell metacharacters, such as in a CI pipeline scanning pull requests, could run arbitrary shell commands. Upgrade to 3.13.6 or 4.0.2; until then, avoid these reports when scanning untrusted code.
