- CVE-2026-107742, 10 Oct 2026
- The 10Web Booster - Website speed optimization, Cache & Page Speed optimizer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'author' parameter in all versions up to, and including, 2.34.8 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable because a comment author Name value containing ' src=' and an event-handler payload contains no HTML tags or quote characters, allowing it to survive WordPress core's sanitize_text_field and land verbatim inside the alt attribute, where the plugin's own str_replace subsequently injects the single quote that breaks out of the attribute context. CVE record
- CVE-2026-82195, 24 Sep 2026
- The 10Web Booster WordPress plugin before 2.34.0 does not restrict access to the routine which issues the shared secret that authenticates its cloud connection, disclosing that secret to unauthenticated visitors and letting them delete it repeatedly, preventing an administrator from completing a legitimate connection. CVE record
- CVE-2026-14287, 19 Aug 2026
- The 10Web Booster WordPress plugin before 2.33.5 does not correctly validate an access token on an unauthenticated request handler and does not escape attacker-supplied stylesheet content before rendering it into the page head, allowing an unauthenticated attacker to store markup that executes as JavaScript in the browser of anonymous visitors to an affected page. CVE record
- CVE-2025-13377, 6 Dec 2025
- The 10Web Booster - Website speed optimization, Cache & Page Speed optimizer plugin for WordPress is vulnerable to arbitrary folder deletion due to insufficient file path validation in the get_cache_dir_for_page_from_url() function in all versions up to, and including, 2.32.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary folders on the server, which can easily lead to a loss of data or a denial of service condition. CVE record
- CVE-2023-5559, 27 Nov 2023
- The 10Web Booster WordPress plugin before 2.24.18 does not validate the option name given to some AJAX actions, allowing unauthenticated users to delete arbitrary options from the database, leading to denial of service. CVE record
