|---|---|---|---|---|---|---|---|
| CVE-2026-45315 | Hig | 0.57 | 8.7 | 0.00 | May 15, 2026 | Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.3, the audio transcription upload endpoint takes the file extension from the user-supplied filename and saves the file under CACHE_DIR/audio/transcriptions/.. The /cache/{path} route serves these files via FileResponse, which sets Content-Type from the on-disk extension and emits no Content-Disposition. A verified user with the default-on chat.stt permission can upload a polyglot WAV+HTML file named pwn.html and trick any other user into opening the resulting URL — the response comes back as text/html and any embedded <script> runs in the Open WebUI origin. This vulnerability is fixed in 0.9.3. | |
| CVE-2021-47943 | Hig | 0.57 | 8.8 | 0.00 | May 10, 2026 | TextPattern CMS 4.8.7 contains a remote code execution vulnerability that allows authenticated attackers to execute arbitrary commands by uploading malicious PHP files through the file upload functionality. Attackers can upload a PHP shell via the Files section in the content area and execute commands by accessing the uploaded file at /textpattern/files/ with GET parameters passed to the system function. | |
| CVE-2021-47937 | Hig | 0.57 | 8.8 | 0.00 | May 10, 2026 | e107 CMS 2.3.0 contains a remote code execution vulnerability that allows authenticated users with theme installation permissions to execute arbitrary commands by uploading malicious theme files. Attackers can upload a crafted theme package through the theme.php endpoint that deploys a web shell to the e107_themes directory, then execute system commands via the payload.php script. | |
| CVE-2026-6692 | Hig | 0.57 | 8.8 | 0.00 | May 7, 2026 | The Slider Revolution plugin for WordPress is vulnerable to Arbitrary File Upload in versions 7.0.0 to 7.0.10 via the '_get_media_url' and '_check_file_path' function. This is due to insufficient file type validation. 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 vulnerability was partially patched in version 7.0.10 and fully patched in version 7.0.11. | |
| CVE-2026-41938 | Hig | 0.57 | 8.8 | 0.00 | May 6, 2026 | Vvveb before version 1.0.8.2 contains an unrestricted file upload vulnerability in the media upload handler that allows authenticated users with media-upload permissions to bypass extension restrictions by uploading a .htaccess file to map .phtml extensions to the PHP handler. Attackers can upload a .phtml file containing arbitrary PHP code and trigger execution by sending an unauthenticated HTTP GET request to the uploaded file, resulting in remote code execution with web server privileges. | |
| CVE-2026-6261 | Hig | 0.57 | 8.8 | 0.00 | May 5, 2026 | The Betheme theme for WordPress is vulnerable to Arbitrary File Upload in versions up to, and including, 28.4. This is due to the upload_icons() function workflow moving and unzipping user-controlled ZIP files into a public uploads directory without validating extracted file types. This makes it possible for authenticated attackers, with author-level access and above, to upload arbitrary files (including PHP) and achieve remote code execution via the Icons icon-pack upload flow. | |
| CVE-2026-38991 | Hig | 0.57 | 8.8 | 0.00 | Apr 29, 2026 | Cockpit 2.13.5 and earlier is affected by a misconfiguration within the Bucket component _isFileTypeAllowed function where a specially crafted filename bypasses an extension filter. This allows an authenticated attacker to rename arbitrary files with the .php file extension enabling arbitrary code to be executed on the underlying server. | |
| CVE-2026-6249 | Hig | 0.57 | 8.8 | 0.00 | Apr 20, 2026 | Vvveb CMS 1.0.8.2 contains a remote code execution vulnerability in its media upload handler that allows authenticated attackers to execute arbitrary operating system commands by uploading a PHP webshell with a .phtml extension. Attackers can bypass the extension deny-list and upload malicious files to the publicly accessible media directory, then request the file over HTTP to achieve full server compromise. | |
| CVE-2026-40488 | Hig | 0.57 | 8.8 | 0.00 | Apr 20, 2026 | Magento Long Term Support (LTS) is an unofficial, community-driven project provides an alternative to the Magento Community Edition e-commerce platform with a high level of backward compatibility. Prior to version 20.17.0, the product custom option file upload in OpenMage LTS uses an incomplete blocklist (`forbidden_extensions = php,exe`) to prevent dangerous file uploads. This blocklist can be trivially bypassed by using alternative PHP-executable extensions such as `.phtml`, `.phar`, `.php3`, `.php4`, `.php5`, `.php7`, and `.pht`. Files are stored in the publicly accessible `media/custom_options/quote/` directory, which lacks server-side execution restrictions for some configurations, enabling Remote Code Execution if this directory is not explicitly denied script execution. Version 20.17.0 patches the issue. | |
| CVE-2026-6518 | Hig | 0.57 | 8.8 | 0.00 | Apr 18, 2026 | The CMP – Coming Soon & Maintenance Plugin by NiteoThemes plugin for WordPress is vulnerable to arbitrary file upload and remote code execution in all versions up to, and including, 4.1.16 via the `cmp_theme_update_install` AJAX action. This is due to the function only checking for the `publish_pages` capability (available to Editors and above) instead of `manage_options` (Administrators only), combined with a lack of proper validation on the user-supplied file URL and no verification of the downloaded file's content before extraction. This makes it possible for authenticated attackers, with Administrator-level access and above, to force the server to download and extract a malicious ZIP file from a remote attacker-controlled URL into a web-accessible directory (`wp-content/plugins/cmp-premium-themes/`), resulting in remote code execution. Due to the lack of a nonce for Editors, they are unable to exploit this vulnerability. | |
| CVE-2026-40040 | Hig | 0.57 | 8.8 | 0.00 | Apr 13, 2026 | Pachno 1.0.6 contains an unrestricted file upload vulnerability that allows authenticated users to upload arbitrary file types by bypassing ineffective extension filtering to the /uploadfile endpoint. Attackers can upload executable files .php5 scripts to web-accessible directories and execute them to achieve remote code execution on the server. | |
| CVE-2026-35164 | Hig | 0.57 | 8.8 | 0.00 | Apr 6, 2026 | Brave CMS is an open-source CMS. Prior to 2.0.6, an unrestricted file upload vulnerability exists in the CKEditor upload functionality. It is found in app/Http/Controllers/Dashboard/CkEditorController.php within the ckupload method. The method fails to validate uploaded file types and relies entirely on user input. This allows an authenticated user to upload executable PHP scripts and gain Remote Code Execution. This vulnerability is fixed in 2.0.6. | |
| CVE-2026-35047 | Cri | 0.57 | 9.8 | 0.00 | Apr 6, 2026 | Brave CMS is an open-source CMS. Prior to 2.0.6, an Unrestricted File Upload vulnerability in the CKEditor endpoint allows attackers to upload arbitrary files, including executable scripts. This may lead to Remote Code Execution (RCE) on the server, potentially resulting in full system compromise, data exfiltration, or service disruption. All users running affected versions of BraveCMS are impacted. This vulnerability is fixed in 2.0.6. | |
| CVE-2019-25673 | Hig | 0.57 | 8.8 | 0.00 | Apr 5, 2026 | UniSharp Laravel File Manager v2.0.0-alpha7 and v2.0 contain an arbitrary file upload vulnerability that allows authenticated attackers to upload malicious files by sending multipart form data to the upload endpoint. Attackers can upload PHP files with the type parameter set to Files and execute arbitrary code by accessing the uploaded file through the working directory path. | |
| CVE-2025-59710 | Hig | 0.57 | 8.8 | 0.00 | Apr 3, 2026 | An issue was discovered in Biztalk360 before 11.5. Because of incorrect access control, any user is able to request the loading a DLL file. During the loading, a method is called. An attacker can craft a malicious DLL, upload it to the server, and use it to achieve remote code execution on the server. | |
| CVE-2026-34735 | Hig | 0.57 | — | 0.00 | Apr 2, 2026 | The Hytale Modding Wiki is a free service for Hytale mods to host their documentation & wikis. In version 1.2.0 and prior, the quickUpload() endpoint validates uploaded files by checking their MIME type (via PHP's finfo, which inspects file contents) but constructs the stored filename using the client-supplied file extension from getClientOriginalExtension(). These two checks are independent: an attacker can upload a file whose content passes the MIME allowlist while using a .php extension. The file is stored on the public disk and is directly accessible via URL, allowing server-side code execution. At time of publication no known patches exist. | |
| CVE-2026-33687 | Hig | 0.57 | 8.8 | 0.00 | Mar 26, 2026 | Sharp is a content management framework built for Laravel as a package. Versions prior to 9.20.0 contain a vulnerability in the file upload endpoint that allows authenticated users to bypass all file type restrictions. The upload endpoint within the `ApiFormUploadController` accepts a client-controlled `validation_rule` parameter. This parameter is directly passed into the Laravel validator without sufficient server-side enforcement. By intercepting the request and sending `validation_rule[]=file`, an attacker can completely bypass all MIME type and file extension restrictions. This issue has been addressed in version 9.20.0 by removing the client-controlled validation rules and strictly defining upload rules server-side. As a workaround, ensure that the storage disk used for Sharp uploads is strictly private. Under default configurations, an attacker cannot directly execute uploaded PHP files unless a public disk configuration is explicitly used. | |
| CVE-2026-3533 | Hig | 0.57 | 8.8 | 0.00 | Mar 24, 2026 | The Jupiter X Core plugin for WordPress is vulnerable to limited file uploads due to missing authorization on import_popup_templates() function as well as insufficient file type validation in the upload_files() function in all versions up to, and including, 4.14.1. This makes it possible for Authenticated attackers with Subscriber-level access and above, to upload files with dangerous types that can lead to Remote Code Execution on servers configured to handle .phar files as executable PHP (e.g., Apache+mod_php), or Stored Cross-Site Scripting via .svg, .dfxp, or .xhtml files upload on any server configuration | |
| CVE-2026-32989 | Hig | 0.57 | 8.8 | 0.00 | Mar 20, 2026 | Precurio Intranet Portal 4.4 contains a cross-site request forgery vulnerability that allows attackers to induce authenticated users to submit crafted requests to a profile update endpoint handling file uploads. Attackers can exploit this to upload executable files to web-accessible locations, leading to arbitrary code execution in the context of the web server. | |
| CVE-2025-67260 | Hig | 0.57 | 8.8 | 0.00 | Mar 20, 2026 | The Terrapack software, from ASTER TEC / ASTER S.p.A., with the indicated components and versions has a file upload vulnerability that may allow attackers to execute arbitrary code. Vulnerable components include Terrapack TkWebCoreNG:: 1.0.20200914, Terrapack TKServerCGI 2.5.4.150, and Terrapack TpkWebGIS Client 1.0.0. |
