Description

Statmatic is a Laravel and Git powered content management system (CMS). Starting in version 6.0.0 and prior to version 6.4.0, Authenticated Control Panel users may under certain conditions obtain elevated privileges without completing the intended verification step. This can allow access to sensitive operations and, depending on the user’s existing permissions, may lead to privilege escalation. This has been fixed in 6.4.0.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
