WP Upload Restriction — Vulnerabilities & Security Advisories 3

WP Upload Restriction is a WordPress plugin designed to control file upload capabilities and restrict access to upload functionality. Historically, it has been susceptible to multiple critical vulnerabilities including Remote Code Execution (RCE), Cross-Site Scripting (XSS), and privilege escalation, primarily stemming from insufficient input validation and improper access controls. The plugin's security issues have allowed attackers to upload malicious files, execute arbitrary code, and bypass security restrictions. With three CVEs documented, these vulnerabilities have enabled unauthorized access and potential system compromise, highlighting the risks of inadequate file handling and permission management in WordPress environments.
