Oct 16, 202610Web Booster – Website speed optimization, Cache & Page Speed optimizer: A limited file writeCVE-2026-103896 · affects up to 2.34.5 · reported by WordfenceHigh 7.5
The 10Web Booster – Website speed optimization, Cache & Page Speed optimizer plugin for WordPress is vulnerable to a limited file write via path traversal in versions up to, and including, 2.34.5 This is due to the OptimizerWebPageCache::get_cache_file_dir() function concatenating raw, unsanitized $_GET parameter names and values into the on-disk cache path, and the cache_content() sink calling mkdir() and file_put_contents() on the result with no realpath containment check — unlike the sibling delete_page_cache(), which does perform one. This makes it possible for unauthenticated attackers to create arbitrary directories (mode 0777, recursively) outside the cache root and write a cached page into them. The write is LIMITED: the filename is always 'source.html', so the extension is fixed, and the content is the rendered page buffer rather than attacker-supplied data. PHP files cannot be written and code execution is not possible; the demonstrated impact is cache poisoning and arbitrary directory creation.

Oct 15, 202610Web Booster – Website speed optimization, Cache & Page Speed optimizer: Arbitrary File UploadCVE-2026-108587 · affects up to 2.34.10 · reported by WordfenceCritical 9.8
The 10Web Booster – Website speed optimization, Cache & Page Speed optimizer plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.34.10 via the compressCustom function. This is due to missing file type validation and extension filtering on the page_id parameter, combined with a world-readable leaked nonce that bypasses authentication checks. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. This exploit chain requires obtaining the plugin's REST nonce (tenwebio_rest), which is automatically serialized to a world-readable file under wp-content/uploads/ whenever a bulk optimisation batch pauses; because the nonce is generated in a cron/loopback context with a user ID of 0, it is valid for unauthenticated visitors.

Oct 10, 202610Web Booster – Website speed optimization, Cache & Page Speed optimizer: Stored Cross-Site ScriptingCVE-2026-107742 · affects up to 2.34.8 · reported by WordfenceHigh 7.2
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.

Sep 24, 202610Web Booster: Does not restrict access to the routineCVE-2026-82195 · fixed in 2.34.0 · reported by WPScanMedium 6.5
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.
Aug 19, 202610Web Booster: 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 headCVE-2026-14287 · fixed in 2.33.5 · reported by WPScanMedium 4.7
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.
Dec 6, 202510Web Booster – Website speed optimization, Cache & Page Speed optimizer: Arbitrary folder deletionCVE-2025-13377 · affects up to 2.32.7 · reported by WordfenceCritical 9.6
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.
Nov 27, 202310Web Booster: Does not validate the option name given to some AJAX actionsCVE-2023-5559 · fixed in 2.24.18 · reported by WPScanCritical 9.1
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.
