CVE-2026-93031 2026-09-19 8.8 High
The WP Cloud Plugins Use-your-Drive, Out-of-the-Box, Share-one-Drive, and Lets-Box plugins for WordPress are vulnerable to Arbitrary File Upload in all versions from 2.0 up to, and including, 3.8.3 via the download_file_to_uploads function. This is due to the import action being registered for unauthenticated users via wp_ajax_nopriv_, a missing capability check in can_import(), and the imported file's extension and contents not being validated against get_allowed_mime_types() before it is written to the uploads directory. 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.
CVE-2026-87935 2 Ichurakov, Wordpress 2 Paid Downloads, Wordpress 2026-09-19 8.1 High
The Paid Downloads plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.15 via the admin_request_handler function. This is due to missing authorization and file type validation in the admin_request_handler function, which is reachable unauthenticated via is_admin() returning true for /wp-admin/admin-post.php. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. On Apache servers where AllowOverride is enabled, an .htaccess file placed in the upload directory may block direct HTTP retrieval of uploaded files, limiting exploitability to stacks that do not honor .htaccess directives such as nginx, LiteSpeed, and Apache with AllowOverride None.
CVE-2026-84434 2026-09-19 9.8 Critical
The Gravity Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.1.0.4 via the upload_file function. This is due to a mismatch between the field validation pipeline and the file persistence pipeline, where hidden file upload fields bypass extension validation and a rejected file's intact upload state is later passed to upload_file() without re-validation. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. Exploitation requires the targeted form to contain a File Upload field with its Visibility set to 'Hidden'; the vulnerability is reachable by unauthenticated attackers on any publicly accessible form meeting this condition.
CVE-2026-84750 2026-09-19 6.5 Medium
The Ultra Addons for Contact Form 7 WordPress plugin before 3.5.51 does not validate the type or extension of files uploaded through one of its form fields, and stores them at a predictable public path with the attacker-chosen extension intact, allowing unauthenticated users to upload arbitrary files. The PHP handler shipped by default with the Debian and Ubuntu Apache packages maps .phar to PHP alongside .php and .phtml, so on that stack the uploaded file is executed and the issue leads to Remote Code Execution and full site takeover. Where the host routes only .php to the PHP handler, the same file is instead served from the site's own origin with its script intact, leading to Stored Cross-Site Scripting.
CVE-2026-87796 2 Sh1zen, Wordpress 2 Multi Uploader For Gravity Forms, Wordpress 2026-09-19 9.8 Critical
The Multi Uploader for Gravity Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.1.9 via the move_file function. This is due to insufficient file type validation during chunked upload handling. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
CVE-2026-77929 1 Macwarrior 1 Clipbucket-v5 2026-09-18 8.8 High
ClipBucket v5 before 5.5.3-#182 contains a file upload vulnerability that allows authenticated users to achieve remote code execution by uploading a PHP file with valid image magic bytes through the photo upload endpoint. The FileUpload::manageFile() function in fileupload.class.php fails to update the file extension after MIME validation, allowing an attacker-controlled .php extension to persist on disk and execute as PHP via PHP-FPM when the uploaded file is retrieved.
CVE-2026-56590 2026-09-18 6.4 Medium
HCL BigFix Service Management is affected by an Unrestricted File Upload vulnerability due to improper file validation controls, which could allow an unauthenticated attacker to upload and execute malicious payloads, resulting in a complete server compromise.
CVE-2026-72762 1 N8n 1 N8n 2026-09-18 8.8 High
n8n versions before 1.123.67, 2.31.5, and 2.32.1 contain an arbitrary file write vulnerability in the Edit Image node, which passes its output format parameter to the underlying image library without validation. An authenticated user able to run workflows can supply a crafted format value to write arbitrary files outside the node's working directory on the n8n instance.
CVE-2026-45140 1 Chamilo 1 Chamilo Lms 2026-09-18 9.8 Critical
Chamilo LMS is an open-source learning management system. Prior to 2.0.1, Chamilo LMS allows an unauthenticated remote attacker to execute arbitrary code on the server. The authoritative advisory does not identify the affected endpoint, component, input, or exploitation mechanism. This issue is fixed in version 2.0.1.
CVE-2026-93750 1 Http-cache-semantics Project 1 Http-cache-semantics 2026-09-18 5.9 Medium
http-cache-semantics through 4.2.0 contains a cache validation vulnerability in the _varyMatches() function that fails to properly validate Vary header wildcards due to byte-for-byte string comparison. Attackers can request URLs previously fetched by other clients to receive cached responses intended for different users, disclosing sensitive information across clients.
CVE-2026-92980 2026-09-18 7.2 High
HortusFox-Web prior to version 6.1 contains a remote code execution vulnerability that allows authenticated administrators to execute arbitrary OS commands as the web server user by abusing the Import/Export functionality. Attackers can leverage the Import/Export feature, which is intended solely for data portability, to deploy and execute malicious code on the underlying application server host.
CVE-2026-87928 2 Max-3000, Maxsite 2 Maxsite Cms, Maxsite Cms 2026-09-18 5.4 Medium
MaxSite CMS versions 0.94 through 109.6 contain a cross-site scripting vulnerability in the admin_page upload handler that allows any logged-in user to upload HTML files. Attackers can upload HTML containing malicious scripts to the uploads/_pages/ directory, which executes in visitors' browsers when the file is accessed, enabling persistent stored cross-site scripting attacks.
CVE-2026-92598 1 Nodemailer 1 Nodemailer 2026-09-17 6.5 Medium
Nodemailer before 9.1.0 fails to apply UTS-46 normalization when encoding international domain names, causing the domain resolver to compute a different Punycode A-label than standards-compliant parsers. Attackers can craft recipient addresses with invisible characters or compatibility mappings that pass domain allow-list checks but are delivered to attacker-controlled domains via SMTP.
CVE-2026-92597 1 Nodemailer 1 Nodemailer 2026-09-17 6.5 Medium
Nodemailer versions >= 6.9.16 and < 9.1.0 mis-parse RFC 5322 comments in email addresses: in lib/addressparser, a comment closed immediately before a non-break character causes the tokenizer to concatenate the atoms surrounding the comment instead of treating the comment as folding whitespace that terminates the domain. A recipient address such as user@good-corp.com(x)evil.com is therefore read by Nodemailer as the single domain good-corp.comevil.com (registrable domain comevil.com, which an attacker can register) and used for both the SMTP envelope (RCPT TO) and the emitted To:/From: headers, while a conformant RFC 5322 parser terminates the domain at the comment and reads good-corp.com. An application that validates the recipient domain with a strict RFC 5322 parser (without inspecting parse defects) or a naive prefix/substring allow-list and then hands the raw address to Nodemailer can be induced to deliver mail to a domain the attacker controls. Fixed in 9.1.0.
CVE-2026-57581 1 Riganti 1 Dotvvm 2026-09-17 5.3 Medium
DotVVM is an open source MVVM framework for web applications. Prior to 4.2.11, 4.3.15, and 5.0.0-preview09-final, applications with configured file upload storage allow unauthenticated users to submit files directly to DotvvmFileUploadMiddleware without an X-DotVVM-UploadToken generated by the FileUpload component. An attacker can repeatedly upload files and fill application storage, causing denial of service. DotvvmConfiguration.Security.AuthorizeFileUpload can additionally restrict which users may upload files. This issue is fixed in versions 4.2.11, 4.3.15, and 5.0.0-preview09-final.
CVE-2026-50006 1 Julien040 1 Anyquery 2026-09-17 9.1 Critical
Anyquery is an SQL query engine built on top of SQLite. Prior to 0.4.5, anyquery server forwards unauthenticated SQL from its MySQL-compatible server port to SQLite without restricting ATTACH DATABASE filesystem targets. A remote attacker can select any path writable by the Anyquery server process, cause SQLite to create a database file there, and place attacker-controlled table content in that file. This permits arbitrary file creation or overwrite, causing filesystem integrity loss and denial of service; remote code execution is possible only when another service interprets the written file or the process has a suitably privileged writable target. This issue is fixed in version 0.4.5.
CVE-2026-82793 1 Contec 2 Can-2-usb, Can-2-wf 2026-09-17 7.2 High
Unrestricted upload of file with dangerous type issue exists in Contec CAN 2.0B Communication Wireless LAN / USB Converter Unit. If a specially crafted file is uploaded by a remote authenticated attacker, arbitrary code may be executed on the product.
