Title
ProSolution WP Client <= 2.0.10 - Unauthenticated Arbitrary File Upload via Content-Disposition Header Filename Override
Summary
The ProSolution WP Client plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.0.10 via the proSol_handleFileUpload function. This is due to missing validation of the attacker-controlled Content-Disposition header filename, which overrides the allow-listed multipart filename before the file is saved, and a post-save extension check that fails to delete the already-written file. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. The nonce required to reach the upload handler is publicly exposed via wp_localize_script on any front-end page rendering the job portal shortcode, allowing unauthenticated visitors to obtain a valid nonce and bypass that gating check entirely.

Title
ProSolution WP Client <= 2.0.8 - Unauthenticated Arbitrary File Deletion via 'newfilename' and 'filename' Parameters
Summary
The ProSolution WP Client plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the proSol_fileDeleteProcess function in all versions up to, and including, 2.0.8. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). An attacker must first call the proSol_fileUploadModalProcess handler to poison their own session with a path-traversal key, then call proSol_fileDeleteProcess with that key as the filename parameter; both steps require only the publicly exposed frontend nonce.

Title
ProSolution WP Client <= 2.0.0 - Unauthenticated Arbitrary File Upload via 'files'
Summary
The ProSolution WP Client plugin for WordPress is vulnerable to Arbitrary File Upload in versions up to, and including, 2.0.0. This is due to an array validation mismatch where only the first file in the upload array undergoes extension and MIME type validation, while all files are processed and uploaded to a web-accessible directory. This makes it possible for unauthenticated attackers to upload malicious PHP files and achieve remote code execution by sending a valid first file followed by a malicious file.

Summary
The ProSolution WP Client plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the proSol_fileDeleteProcess function in all versions up to, and including, 2.0.8. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). An attacker must first call the proSol_fileUploadModalProcess handler to poison their own session with a path-traversal key, then call proSol_fileDeleteProcess with that key as the filename parameter; both steps require only the publicly exposed frontend nonce.

Title
ProSolution WP Client <= 2.0.10 - Unauthenticated Arbitrary File Upload via Content-Disposition Header Filename Override
Summary
The ProSolution WP Client plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.0.10 via the proSol_handleFileUpload function. This is due to missing validation of the attacker-controlled Content-Disposition header filename, which overrides the allow-listed multipart filename before the file is saved, and a post-save extension check that fails to delete the already-written file. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. The nonce required to reach the upload handler is publicly exposed via wp_localize_script on any front-end page rendering the job portal shortcode, allowing unauthenticated visitors to obtain a valid nonce and bypass that gating check entirely.

Title
ProSolution WP Client <= 2.0.0 - Unauthenticated Arbitrary File Upload via 'files'
Summary
The ProSolution WP Client plugin for WordPress is vulnerable to Arbitrary File Upload in versions up to, and including, 2.0.0. This is due to an array validation mismatch where only the first file in the upload array undergoes extension and MIME type validation, while all files are processed and uploaded to a web-accessible directory. This makes it possible for unauthenticated attackers to upload malicious PHP files and achieve remote code execution by sending a valid first file followed by a malicious file.
