- CVE-2026-2383, 27 Feb 2026
- The Simple Download Monitor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via custom field in all versions up to, and including, 4.0.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
- CVE-2025-8977, 28 Aug 2025
- The Simple Download Monitor plugin for WordPress is vulnerable to time-based SQL Injection via the order parameter in all versions up to, and including, 3.9.33 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Contributor-level access and above, and permissions granted by an Administrator, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. CVE record
- CVE-2021-24692, 14 Mar 2022

- CVE-2021-24693, 8 Nov 2021
