Joomla Extension - OrdaSoft.com - Authenticated, Privileged Remote Code Execution in OrdaSoft Joomla Gallery extension for Joomla < 6.2.7 - The extensions saveWatermark() copied an uploaded file into a web-accessible directory using the client-supplied filename exactly as sent, with no extension check, no content check, and no filename sanitisation of any kind. An authenticated core.manage user could upload a .php file disguised with an image Content-Type header and execute it directly by requesting the resulting path.

CVE-2026-941048.8 HIG—
——0NivoCart through 2.4.0 contains an arbitrary file upload vulnerability in the File Manager multi() endpoint that fails to validate file extensions for new filenames or when chunks parameter is 2 or higher. Attackers with view-only back-office access can upload PHP files to the web-accessible image/data/ directory and execute them for remote code execution.21hCVE-2026-816507.2 HIG3.7%
——1The Photo Gallery, Sliders, Proofing and WordPress plugin before 4.5.0 does not correctly validate the extensions of files extracted from an uploaded archive, due to a variable being reused as a loop counter so that the check always passes, allowing users granted its gallery-management capability by an administrator to write arbitrary files into a web-accessible directory and, on hosts that execute them, run arbitrary code.19hCVE-2026-847506.5 MED18.8%
——6The Ultra Addons for Contact Form 7 WordPress plugin before 3.5.51 does not validate the type or extension of files uploaded through one of its form fields, and stores them at a predictable public path with the attacker-chosen extension intact, allowing unauthenticated users to upload arbitrary files. The PHP handler shipped by default with the Debian and Ubuntu Apache packages maps .phar to PHP alongside .php and .phtml, so on that stack the uploaded file is executed and the issue leads to Remote Code Execution and full site takeover. Where the host routes only .php to the PHP handler, the same file is instead served from the site's own origin with its script intact, leading to Stored Cross-Site Scripting.2dCVE-2026-844349.8 CRI51.6%
——15The Gravity Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.1.0.4 via the upload_file function. This is due to a mismatch between the field validation pipeline and the file persistence pipeline, where hidden file upload fields bypass extension validation and a rejected file's intact upload state is later passed to upload_file() without re-validation. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. Exploitation requires the targeted form to contain a File Upload field with its Visibility set to 'Hidden'; the vulnerability is reachable by unauthenticated attackers on any publicly accessible form meeting this condition.2dCVE-2026-930318.8 HIG46.6%
——14The WP Cloud Plugins Use-your-Drive, Out-of-the-Box, Share-one-Drive, and Lets-Box plugins for WordPress are vulnerable to Arbitrary File Upload in all versions from 2.0 up to, and including, 3.8.3 via the download_file_to_uploads function. This is due to the import action being registered for unauthenticated users via wp_ajax_nopriv_, a missing capability check in can_import(), and the imported file's extension and contents not being validated against get_allowed_mime_types() before it is written to the uploads directory. 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.2dCVE-2026-779298.8 HIG42.5%
——13ClipBucket v5 before 5.5.3-#182 contains a file upload vulnerability that allows authenticated users to achieve remote code execution by uploading a PHP file with valid image magic bytes through the photo upload endpoint. The FileUpload::manageFile() function in fileupload.class.php fails to update the file extension after MIME validation, allowing an attacker-controlled .php extension to persist on disk and execute as PHP via PHP-FPM when the uploaded file is retrieved.3d
