Arbitrary File Upload

A critical arbitrary file upload vulnerability (CVE-2026-14270) in the Extra Checkout Options plugin for WordPress, affecting versions up to and including 2.3.2, allows low-privileged authenticated users to modify upload allowlists and upload malicious PHP files via an AJAX action, ultimately achieving remote code execution on the server.

The Easy Digital Downloads plugin for WordPress versions up to and including 3.6.9 is vulnerable to Arbitrary File Upload (CVE-2026-12476) due to insufficient file type validation, allowing authenticated attackers with Shop Manager-level access or higher to upload arbitrary files which can lead to remote code execution.

The WPForms Pro plugin for WordPress, in versions up to and including 1.10.1.1, is vulnerable to arbitrary file upload via the ajax_chunk_upload_finalize function, allowing unauthenticated attackers to upload executable files due to improper file type validation occurring after file contents are written to disk, which can lead to remote code execution on the affected server.

An arbitrary file upload vulnerability exists in the GoDAM WordPress plugin versions up to and including 1.12.2 due to insufficient file type validation in the `save_video_file()` function, allowing unauthenticated attackers to upload arbitrary files to the server and potentially achieve remote code execution.

An authenticated attacker with Administrator-level access can exploit CVE-2026-1771 in the MapSVG WordPress plugin, affecting versions up to 8.14.0, due to missing file type validation, enabling arbitrary file uploads and potentially leading to remote code execution on the server.

A high-severity arbitrary file upload vulnerability, CVE-2026-13430, exists in all versions up to 1.13.1 of the Post Export Import with Media plugin for WordPress, allowing authenticated administrators to upload executable web shells via a trailing-dot filename bypass, leading to remote code execution.

An unauthenticated arbitrary file upload vulnerability (CVE-2026-14894) exists in the Super Forms - Drag & Drop Form Builder plugin for WordPress, affecting all versions up to and including 6.3.313, allowing unauthenticated attackers to upload executable files via the `submit_form` AJAX handler, leading to remote code execution after trivial nonce bypass.

The Blocksy Companion plugin for WordPress, specifically the premium version (blocksy-companion-pro) with the WooCommerce Extra (Advanced Reviews) and Custom Fonts extensions active, is vulnerable to Arbitrary File Upload (CVE-2026-15158). This flaw, present in versions up to and including 2.1.46, arises from improper file type validation within the `save_attachments` function, allowing double-extension files like `shell.woff2.php` to bypass MIME checks, which unauthenticated attackers can exploit to upload executable files, leading to remote code execution.

A public exploit has been released for an arbitrary file upload vulnerability in Joomla Page Builder CK version 3.5.10, which allows an unauthenticated attacker to upload malicious files to the server, potentially leading to remote code execution and full system compromise.

Authenticated attackers with Custom-level access or higher can exploit CVE-2026-14489, a missing file type validation vulnerability (CWE-434) in the `connect()` function of the WHMCS Bridge plugin for WordPress versions up to and including 6.9, to upload arbitrary files, potentially leading to remote code execution.

DreamMaker by Interinfo is vulnerable to arbitrary file upload, allowing privileged remote attackers to upload and execute web shell backdoors, enabling arbitrary code execution on the server.

The GutenBee – Gutenberg Blocks plugin for WordPress is vulnerable to arbitrary file upload, allowing authenticated attackers with author-level access to achieve remote code execution by uploading executable files with double extensions.

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 versions up to 5.6, allowing unauthenticated attackers to upload arbitrary files and potentially achieve remote code execution if a signature custom field is added to the booking form.

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, allowing unauthenticated attackers to upload arbitrary files and potentially achieve remote code execution.

The Piotnet Addons for Elementor Pro plugin for WordPress, versions up to 7.1.70, is vulnerable to unauthenticated arbitrary file upload due to insufficient file type validation in the 'pafe_ajax_form_builder' function, potentially leading to remote code execution.

The Career Section plugin for WordPress is vulnerable to arbitrary file upload in versions up to 1.7 due to missing file type validation in the CV upload handler, potentially leading to remote code execution.

A privileged remote attacker can exploit CVE-2026-7490 in Sunnet CTMS and CPAS to upload and execute web shell backdoors, leading to arbitrary code execution on the server.

The Betheme theme for WordPress is vulnerable to arbitrary file upload, allowing authenticated attackers with author-level privileges or higher to upload arbitrary files, including PHP, leading to remote code execution.

The livewire-markdown-editor versions before v1.3 contain an arbitrary file upload vulnerability in the MarkdownEditor::updatedAttachments() Livewire handler, allowing authenticated users to upload any file type, potentially leading to stored XSS, phishing, malware distribution, and markdown injection.
