CVE-2023-6634 (GCVE-0-2023-6634)
Vulnerability from cvelistv5 – Published: 2024-01-11 08:32 – Updated: 2026-04-08 16:41Title
LearnPress <= 4.2.5.7 - Command Injection
Summary
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.
