## What is CVE-2024-12155?

CVE-2024-12155 is a critical missing authorization vulnerability in matthias-reuter SV100 Companion, published on 6 Dec 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The SV100 Companion plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the settings_import() function in all versions up to, and including, 2.0.02. This makes it possible for unauthenticated attackers to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site. CVE-2024-54229 may be a duplicate of this issue.
