CVE-2023-6634: Thimpress Learnpress

Critical severity, CVSS 9.8. EPSS: 8.5% chance of exploitation in the next 30 days.

The LearnPress plugin for WordPress is vulnerable to Command Injection in all versions up to, and including, 4.2.5.7 via the get_content function. This is due to the plugin making use of the call_user_func function with user input. This makes it possible for unauthenticated attackers to execute any public function with one parameter, which could result in remote code execution.
