## Technical details

The affiliate-toolkit WordPress plugin is vulnerable to Remote Code Execution (RCE) due to improper input validation within its templating system. Specifically, the plugin utilizes the BladeOne templating engine's runString() method, which processes user-provided template content and executes it as PHP code using eval() without adequate sanitization or sandboxing. An authenticated attacker with Editor-level privileges or higher can exploit this by injecting arbitrary PHP code into a plugin template. This vulnerability is tracked as CWE-94 (Improper Control of Generation of Code). The issue is present in all versions up to and including 3.8.5.
