HAX CMS helps manage microsite universe with PHP or NodeJs backends. Prior to version 26.0.0 of HAX CMS PHP, the `saveFile` endpoint validates upload extensions case-insensitively and writes the filename to disk verbatim, but the `.htaccess` rule that forces `Content-Disposition: attachment` on HTML files is case-sensitive. An HTML file uploaded with an uppercase extension (`.HTML`, `.Html`, `.HTM`) is still served as `text/html` but the forced-download header never applies, so the browser renders it inline and executes any embedded JavaScript in the HAXcms origin. This bypasses the mitigation shipped for CVE-2026-22704. Version 26.0.0 contains a fix.
A vulnerability in dfir-iris iris-web prior to version 2.4.28 allows unrestricted upload of files with dangerous types due to improper validation. This can be exploited to host phishing pages and also leads to a Cross-Site Scripting (XSS) vulnerability. The issue is addressed in version 2.4.28.
DreamMaker developed by Interinfo has an Arbitrary File Upload vulnerability, allowing privileged remote attackers to upload and execute web shell backdoors, thereby enabling arbitrary code execution on the server.

The GutenBee – Gutenberg Blocks plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.20.1 via the gutenbee_file_and_ext_json function. This is due to a flawed strpos() substring check that only verifies whether the filename contains the string '.json' rather than confirming the filename ends with a .json extension, allowing double-extension filenames like shell.json.php to bypass validation. This makes it possible for authenticated attackers, with author-level access and above, to upload files that may be executable, which makes remote code execution possible.
The Crawlomatic Multipage Scraper Post Generator plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.7.2 via the filter_content function. This is due to passing the attacker-supplied 'callback_raw' shortcode attribute directly into call_user_func() with no sanitization or allowlist validation, relying solely on an is_callable() check that permits dangerous PHP built-ins such as system, shell_exec, exec, passthru, and assert. This makes it possible for authenticated attackers, with author-level access and above, to execute code on the server. An identical sink exists for the 'callback' attribute, providing a second independent vector through the same shortcode.
FacturaScripts is an open source accounting and invoicing software. In 2025.81 and earlier, an authenticated unrestricted file upload vulnerability exists in FacturaScripts' product image upload functionality. An attacker with valid credentials can upload a PHP file disguised as a GIF image (using a GIF89a header), bypassing MIME type validation. The file is stored with its original extension, including executable extensions such as .php. The vulnerability exists the addImageAction() method of Core/Lib/ExtendedController/ProductImagesTrait.php.
Dalfox is a powerful open-source XSS scanner and utility focused on automation. Prior to 2.13.0, when dalfox is run in REST API server mode, the output, output-all, and debug fields in model.Options are JSON-tagged and deserialized directly from the attacker's request body, then propagated unchanged through dalfox.Initialize into the scan engine's logging path. The logger opens the attacker-supplied path with os.O_APPEND|os.O_CREATE|os.O_WRONLY and writes scan log lines to it. Critically, this file write block lives outside the IsLibrary guard in DalLog, so it executes even in server/library mode where file output was never intended to operate. Because no API key is required in the default configuration, an unauthenticated network caller can create or append to any file writable by the dalfox process on the host filesystem. This vulnerability is fixed in 2.13.0.
The BookingPress Pro plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'bookingpress_validate_submitted_booking_form_func' function in all versions up to, and including, 5.6. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Note: The vulnerability can only be exploited if a signature custom field is added to the booking form.
Improper input validation, Unrestricted upload of file with dangerous type vulnerability in Gmission Web Fax allows Remote Code Inclusion.
This issue affects Web Fax: from 3.0 before 3.1.
Unrestricted Upload of File with Dangerous Type vulnerability in WP Swings Gift Cards For WooCommerce Pro allows Using Malicious Files.
This issue affects Gift Cards For WooCommerce Pro: from n/a through 4.2.6.
CVE-2026-9102 is a critical path traversal vulnerability in Altium Enterprise Server's ComparisonService. It arises from insufficient filename sanitization in the Gerber file upload APIs, allowing an authenticated user to write arbitrary files outside the intended temporary directory. This can lead to remote code execution, service takeover, or denial of service by overwriting binaries or configuration files.
The ProSolution WP Client plugin for WordPress is vulnerable to Arbitrary File Upload in versions up to, and including, 2.0.0. This is due to an array validation mismatch where only the first file in the upload array undergoes extension and MIME type validation, while all files are processed and uploaded to a web-accessible directory. This makes it possible for unauthenticated attackers to upload malicious PHP files and achieve remote code execution by sending a valid first file followed by a malicious file.
The Piotnet Forms plugin for WordPress is vulnerable to arbitrary file upload due to missing file type validation in the 'piotnetforms_ajax_form_builder' function in all versions up to, and including, 2.1.40. The plugin uses an incomplete extension blacklist that only blocks php, phpt, php5, php7, and exe extensions, while allowing dangerous extensions such as .phar or .phtml to be uploaded. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Note: The exploit can only be exploited if a file field is added to the form.
CVE-2026-4885 is a critical vulnerability in the Piotnet Addons for Elementor Pro WordPress plugin that allows unauthenticated attackers to upload arbitrary files due to insufficient file type validation. The plugin's incomplete blacklist blocks only a few dangerous extensions but allows others like . phar and . phtml, which can lead to remote code execution if a file upload field is present in a form. This affects all versions up to and including 7.1.70. No official patch or remediation guidance is currently available from the vendor.
FacturaScripts versions 2026 and below contain a critical vulnerability in the Plugins::add() function that allows a Zip Slip attack via improper validation of file paths in uploaded ZIP archives. This flaw enables an attacker to perform arbitrary file writes and remote code execution by overwriting sensitive PHP files outside the intended plugins directory. The vulnerability arises because the testZipFile function only checks for a single root folder but does not sanitize file paths within that folder, allowing path traversal sequences like .. /.. / to escape the directory. This issue is fixed in version 2026.1.
SzafirHost verifies the signature of the downloaded JAR file using class JarInputStream (reading from the beginning of the file), but loads classes using class JarFile/URLClassLoader (reading the Central Directory from the end). It can lead to remote code execution by allowing an attacker to combine a genuine, signed JAR file with a malicious ZIP file, causing the verification to pass but the malicious class to be loaded.
This issue was fixed in version 1.2.1.
Strapi versions prior to 5.33.3 contain a vulnerability in the Upload plugin's Content API endpoints where MIME type restrictions configured by administrators were not enforced. This allowed authenticated users with upload permissions to upload disallowed file types such as HTML and SVG. When served from the same origin as the admin panel, these files could execute JavaScript in the admin context, potentially leading to admin session hijacking and unauthorized administrative actions. The issue was fixed in version 5.33.3 by unifying the security checks across all upload entry points.
The Career Section plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.7 via the CV upload handler. This is due to missing file type validation. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.
