Description
This extension provides a dedicated set of quality rules that have been designed to check your PHP source code for user input security defects or violations. These quality rules are based on the user input security checks provided by the open source static analysis tool called Psalm (see https://psalm.dev/) and are in addition to the PHP quality rules provided by com.castsoftware.php (this is a dependent extension and the Psalm Security Rules extension will run its quality rules against the results of the PHP Analyzer analysis).
The following Psalm user input security checks are supported by this extension:
- https://psalm.dev/docs/running_psalm/issues/TaintedCallable/
