Insufficient input escaping was applied to the PHP unit webrunner admin tool.
NOTE: It is important to note that this update is only flagged as a precautionary measure, as it may provide limited CLI access to Moodle site admins. This may be considered a security risk in circumstances where admins do not ordinarily have access to the server CLI and/or in some hosting situations where site admins are not considered trusted users. This tool will also be removed entirely from Moodle 3.9.
