Mautic: Improper Validation of Specified Quantity in Input

CVE-2022-25769 is a critical-severity improper validation of specified quantity in input vulnerability in Mautic, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 3.3.5, 4.2.0 as the first without the flaw, so updating Mautic to one of those releases or later removes the exposure. There is no confirmed exploitation so far.

Official description

ImpactThe default .htaccess file has some restrictions in the access to PHP files to only allow specific PHP files to be executed in the root of the application. This logic isn't correct, as the regex in the second FilesMatch only checks the filename, not the full path.

The underlying weakness: Improper Validation of Specified Quantity in Input
