HAX CMS helps manage microsite universe with PHP or NodeJs backends. Starting in version 11.0.6 and prior to version 25.0.0, the file upload functionality in HAXCMS PHP only validates file extensions using a regex pattern without checking the actual file content or MIME type. This allows attackers to upload malicious files (e.g., PHP webshells) disguised as legitimate image files, potentially leading to remote code execution. Version 25.0.0 contains a fix for the issue.

CVE-2026-364677.2 HIG—
——0Unrestricted Upload of File with Dangerous Type in core/modules/media.php in CuteNews v.2.1.2 allows remote authenticated users with access to the Media Manager panel to execute arbitrary code in the context of the web application, leading to remote server access by triggering a reverse shell.7hCVE-2026-94383——
——0The MISP blocklist workflow module accepted a user-supplied blocklist filename parameter without validating the file extension. The only sanitization applied was basename() to strip path components and a check for empty or dot values. A site administrator could specify a filename with an arbitrary extension that would be placed in the MISP export directory. If the underlying web server is configured to interpret and execute scripts from that directory, the resulting file could be invoked, leading to arbitrary code execution in the context of the web server process.
The vulnerability requires the attacker to hold site-administrator privileges within MISP, as the blocklist workflow module is restricted to that role. No additional user interaction is required beyond triggering the workflow action with a crafted filename parameter. The impact is full compromise of the MISP server's confidentiality, integrity, and availability, as arbitrary script execution grants the attacker the same privileges as the web server user.

——1The Web to Print Online Designer WordPress plugin before 2.15.0 does not validate the type or extension of uploaded files, and hands the token protecting those uploads to any visitor who asks for it, allowing unauthenticated attackers to upload arbitrary files, including PHP ones, and run code on the server.8hCVE-2026-88857—39.5%
——12Joomla 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.6hCVE-2026-941048.8 HIG50.2%
——15NivoCart 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.1dCVE-2026-816507.2 HIG20.4%
——6The 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.10h
