CVE-2026-35047 1 Ajax30 1 Bravecms 2026-06-17 N/A 9.8 CRITICAL
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-2026-34735 2026-06-17 N/A N/A
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-2026-34031 1 Apache 1 Answer 2026-06-17 N/A 6.5 MEDIUM
Unrestricted Upload of File with Dangerous Type vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.0. The server did not sufficiently validate user-supplied image URLs, allowing arbitrary external content to be embedded as profile images, which could expose users to unintended external requests and tracking by third-party servers. Users are recommended to upgrade to version 2.0.1, which fixes the issue.
CVE-2026-34027 2026-06-17 N/A N/A
The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains insufficient server-side file type validation in the /safe/contract/uploadcustomdocuments endpoint. The application validates uploaded files based on the user-controlled HTTP Content-Type value and accepts the upload if this value contains an allowed string such as pdf, jpeg, tiff, or png. An authenticated attacker with any role or permission level can spoof the Content-Type value and upload arbitrary file content.
CVE-2026-33809 1 Golang 1 Tiff 2026-06-17 N/A 5.3 MEDIUM
A maliciously crafted TIFF file can cause image decoding to attempt to allocate up 4GiB of memory, causing either excessive resource consumption or an out-of-memory error.
CVE-2026-33717 1 Wwbn 1 Avideo 2026-06-17 N/A 8.8 HIGH
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `downloadVideoFromDownloadURL()` function in `objects/aVideoEncoder.json.php` saves remote content to a web-accessible temporary directory using the original URL's filename and extension (including `.php`). By providing an invalid `resolution` parameter, an attacker triggers an early `die()` via `forbiddenPage()` before the temp file can be moved or cleaned up, leaving an executable PHP file persistently accessible under the web root at `videos/cache/tmpFile/`. Commit 6da79b43484099a0b660d1544a63c07b633ed3a2 contains a patch.
CVE-2026-33704 1 Chamilo 1 Chamilo Lms 2026-06-17 N/A 7.1 HIGH
Chamilo LMS is a learning management system. Prior to 1.11.38, any authenticated user (including students) can write arbitrary content to files on the server via the BigUpload endpoint. The key parameter controls the filename and the raw POST body becomes the file content. While .php extensions are filtered to .phps, the .pht extension passes through unmodified. On Apache configurations where .pht is handled as PHP, this leads to Remote Code Execution. This vulnerability is fixed in 1.11.38.
CVE-2026-33687 1 Code16 1 Sharp 2026-06-17 N/A 8.8 HIGH
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-2026-33647 1 Wwbn 1 Avideo 2026-06-17 N/A 8.8 HIGH
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `ImageGallery::saveFile()` method validates uploaded file content using `finfo` MIME type detection but derives the saved filename extension from the user-supplied original filename without an allowlist check. An attacker can upload a polyglot file (valid JPEG magic bytes followed by PHP code) with a `.php` extension. The MIME check passes, but the file is saved as an executable `.php` file in a web-accessible directory, achieving Remote Code Execution. Commit 345a8d3ece0ad1e1b71a704c1579cbf885d8f3ae contains a patch.
CVE-2026-33582 1 Apache 1 Answer 2026-06-17 N/A 6.5 MEDIUM
Unrestricted Upload of File with Dangerous Type vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.0. A crafted TIFF image could trigger excessive memory allocation during image decoding, allowing an authenticated user to cause the server process to crash. Users are recommended to upgrade to version 2.0.1, which fixes the issue.
CVE-2026-33435 1 Weblate 1 Weblate 2026-06-17 N/A 8.0 HIGH
Weblate is a web based localization tool. In versions prior to 5.17, the project backup didn't filter Git and Mercurial configuration files which could lead to remote code execution under certain circumstances. This issue has been fixed in version 5.17. If developers are unable to update immediately, they can limit the scope of the vulnerability by restricting access to the project backup, as it is only accessible to users who can create projects.
CVE-2026-33273 1 Icz 1 Matcha Invoice 2026-06-17 N/A 7.2 HIGH
Unrestricted upload of file with dangerous type issue exists in MATCHA INVOICE 2.6.6 and earlier. If this vulnerability is exploited, an arbitrary file may be created by an administrator of the product. As a result, arbitrary code may be executed on the server.
CVE-2026-33071 1 Filerise 1 Filerise 2026-06-17 N/A 4.3 MEDIUM
FileRise is a self-hosted web file manager / WebDAV server. In versions prior to 3.8.0, the WebDAV upload endpoint accepts any file extension including .phtml, .php5, .htaccess, and other server-side executable types, bypassing the filename validation enforced by the regular upload path. In non-default deployments lacking Apache's LocationMatch protection, this leads to remote code execution. When files are uploaded via WebDAV, the createFile() method in FileRiseDirectory.php and the put() method in FileRiseFile.php accept the filename directly from the WebDAV client without any validation. In contrast, the regular upload endpoint in UploadModel::upload() validates filenames against REGEX_FILE_NAME. This issue is fixed in version 3.8.0.
CVE-2026-32989 1 Precurio 1 Intranet Portal 2026-06-17 N/A 8.8 HIGH
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-2026-32985 1 Apereo 1 Xerte Online Toolkits 2026-06-17 N/A 9.8 CRITICAL
Xerte Online Toolkits versions 3.14 and earlier contain an unauthenticated arbitrary file upload vulnerability in the template import functionality that allows remote attackers to execute arbitrary code by uploading a crafted ZIP archive containing malicious PHP payloads. Attackers can bypass authentication checks in the import.php file to upload a template archive with PHP code in the media directory, which gets extracted to a web-accessible path where the malicious PHP can be directly accessed and executed under the web server context.
CVE-2026-32931 1 Chamilo 1 Chamilo Lms 2026-06-17 N/A 7.5 HIGH
Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, an unrestricted file upload vulnerability in the exercise sound upload function allows an authenticated teacher to upload a PHP webshell by spoofing the Content-Type header to audio/mpeg. The uploaded file retains its original .php extension and is placed in a web-accessible directory, enabling Remote Code Execution as the web server user (www-data). This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3.
CVE-2026-32756 1 Admidio 1 Admidio 2026-06-17 N/A 8.8 HIGH
Admidio is an open-source user management solution. Versions 5.0.6 and below contain a critical unrestricted file upload vulnerability in the Documents & Files module. Due to a design flaw in how CSRF token validation and file extension verification interact within UploadHandlerFile.php, an authenticated user with upload permissions can bypass file extension restrictions by intentionally submitting an invalid CSRF token. This allows the upload of arbitrary file types, including PHP scripts, which may lead to Remote Code Execution on the server, resulting in full server compromise, data exfiltration, and lateral movement. This issue has been fixed in version 5.0.7.
CVE-2026-32536 2026-06-17 N/A 9.9 CRITICAL
