Prosolution Wp Client
Monthly
Unauthenticated remote code execution in the ProSolution WP Client WordPress plugin (versions ≤ 2.0.0) allows attackers to upload malicious PHP files to a web-accessible directory by abusing an array validation mismatch in its upload handler. Because only the first file in a multi-file upload array is checked for extension and MIME type while the remaining files are processed unchecked, attackers can pair a benign first file with a PHP webshell to achieve full code execution on the host. No public exploit identified at time of analysis, but the high CVSS 9.8 score and trivially scriptable nature place this in the realistic mass-exploitation tier for WordPress plugins.
