———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.11h CVE-2026-574916.5 MED

——0FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.16.0, FileRise archive extraction does not apply UploadNamePolicy::isAllowedForWrite() before ZipArchive::extractTo() writes entries into the destination directory. An authenticated user with upload and extract permissions can place a blocked extension such as a PHP-family file inside a ZIP and cause it to be written to disk even when normal uploads reject that filename. Post-extraction metadata pruning does not remove the blocked file, so deployments that execute uploaded content may permit code execution. This issue is fixed in version 3.16.0.19h CVE-2026-864618.8 ALT

——0The FV Flowplayer Video Player plugin for WordPress is vulnerable to Limited Arbitrary File Upload in all versions up to, and including, 7.5.54.7212 via the check_mimetype function. This is due to incomplete file type validation in the check_mimetype function — while some extension checking is present, it can be bypassed, allowing attacker-supplied remote file content to be written with insufficient extension enforcement and no MIME check or WordPress upload helper. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. Exploitation requires the plugin's 'profile videos on bio' option to be enabled, as this causes the nonce to be emitted on the subscriber-accessible profile page; without this setting, authenticated users below Editor cannot obtain the required nonce.22h CVE-2026-878559.8 CRÍ

——17The JTL-Connector for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.4.3 via the saveImage() function. This is due to the startSession() function accepting an empty jtlauth parameter as a valid credential, combined with insufficient file type validation in handleImagePush(). This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.1d CVE-2026-1048009.8 CRÍ

——19The AGE-GATE plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.0 via the 'width (and height)' parameter parameter. This is due to missing authentication, capability checks, and nonce verification on the standalone admin.php endpoint, combined with unsanitized injection of POST parameters directly into generated PHP source written to an included file. This makes it possible for unauthenticated attackers to execute code on the server. This is possible because admin.php does not load WordPress and carries no ABSPATH guard, making it a fully unauthenticated entry point regardless of the decorative capability arguments registered via the plugin's simulated menu API.1d CVE-2026-1100029.8 CRÍ

——18The Snazzy Social Media Feed plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.5 via the (file scope) function. This is due to missing WordPress bootstrap, authentication, capability, and nonce checks in the standalone save-to-cache.php script, combined with insufficient sanitization of the pluginURL parameter before it is written to a web-executable PHP file. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. The save-to-cache.php script is directly reachable without loading WordPress; FILTER_SANITIZE_URL — the only filter applied to the pluginURL value — preserves the characters required to craft a valid PHP payload, which is then written verbatim into cached-content/cached-feed.php and immediately executable via a single GET request.1d
