Nodemailer before 9.1.0 IDN/Punycode Domain Allow-list Bypass

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.

DotVVM: Unrestricted file upload

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.

Anyquery: Arbitrary File Write (AFW) which could lead to Remote Code Execution (RCE) via Unrestricted ATTACH DATABASE in Server Mode

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.

undici vulnerable to Denial of Service via unhandled error in WebSocket permessage-deflate decompression

undici bundles a WebSocket client whose permessage-deflate size-limit cleanup removes all listeners from the internal zlib inflate stream, including its error listener, while that stream can still emit. When a remote peer sends a compressed payload that crosses the built-in 128 MiB decompressed-payload limit and then contains a malformed DEFLATE byte, the inflate stream emits a data error with no listener attached, which Node.js treats as a fatal unhandled error and terminates the entire process. Exploitation is remote and unauthenticated, requires no application mistake, and is asymmetric, since roughly 130 KB on the wire expands past the limit and crashes the process, and reconnecting can repeat the crash. This affects undici versions from 6.25.0 up to 6.28.1, from 7.28.0 up to 7.29.1, and from 8.1.0 up to 8.10.2. Users should upgrade to undici 6.28.1, 7.29.1, or 8.10.2.

Contest Gallery <= 32.0.1 - Unauthenticated Arbitrary File Upload via 'baseUrlForFacebook' Parameter

The Contest Gallery – Upload & Vote Photos, Media, Sell with PayPal & Stripe plugin for WordPress is vulnerable to Unauthenticated Arbitrary File Overwrite in all versions up to, and including, 32.0.1 due to insufficient file path validation in the 'baseUrlForFacebook' parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite known files which may lead to remote code execution when certain preconditions are met.

backpack/crud: HasUploadFields keeps the attacker-supplied file extension — public-disk uploads of `shell.php` reach the webserver

backpack/crud provides Create, Read, Update & Delete (CRUD) functions for Backpack, a collection of Laravel packages that help users build custom administration panels. From 6.0.0 until 6.8.14 and 7.0.38, HasUploadFields methods uploadFileToDisk and uploadMultipleFilesToDisk, used through CrudTrait, and the withFiles() path through FileNameGenerator do not internally reject server-executable file types. An authenticated administrator can achieve remote code execution by using an upload-enabled CRUD field without mimes: and mimetypes: validation when the public disk is web-accessible through php artisan storage:link and the web-server and PHP-FPM configuration executes the stored extension. The legacy path preserves an accepted extension and the newer path derives an extension without blocking dangerous types. The package-level restriction is defense in depth and does not replace application-level upload validation. This issue is fixed in versions 6.8.14 and 7.0.38.

Flask-Reuploaded: Extension-denylist bypass via case-folding asymmetry in name-override path (incomplete-fix variant of CVE-2026-27641)

Flask-Reuploaded provides file uploads for Flask. From 1.5.0 until 1.6.0, UploadSet.save(storage, name=...) in src/flask_uploads/flask_uploads.py applies lowercase_ext to the default upload path but uses the case-preserving extension helper for a caller-supplied name before extension_allowed evaluates an AllExcept denylist. An attacker who controls the name override can use a mixed-case dangerous extension to bypass a lowercase denylist and store the file in the served upload directory. Exploitation requires a denylist configuration, a user-influenced name override, and a deployment that resolves or executes extensions case-insensitively; pure allowlists remain protected and path containment is not bypassed. On an execution-capable upload directory, the stored file can execute with the web server's privileges and affect confidentiality, integrity, and availability. This issue is fixed in version 1.6.0.

Anil-matcha Open-Generative-AI S3 Upload upload-binary unrestricted upload

A vulnerability was identified in Anil-matcha Open-Generative-AI up to 1.0.11/2.0.0. Affected by this issue is some unknown functionality of the file /api/upload-binary of the component S3 Upload. Such manipulation of the argument x-proxy-target-url leads to unrestricted upload. The attack may be launched remotely. The name of the patch is f013270957f75e439eaf97eb2a93decb32a4543e. Applying a patch is advised to resolve this issue.

@fastify/middie vulnerable to path-scoped middleware bypass via absolute-form request target

@fastify/middie versions >= 9.1.0 and before 9.3.4 decide whether to run path-scoped middleware by matching against the raw request target, while the Fastify router resolves an absolute-form request target to its path before dispatching. Because the two layers evaluate different strings, a request using an absolute-form target reaches the route handler while the path-scoped middleware, such as authentication or authorization, is skipped. An unauthenticated network attacker can use this to bypass path-based access controls in a Fastify application that relies on middie for those controls. Users should upgrade to @fastify/middie 9.3.4 or later.

fast-uri vulnerable to mailto header injection via percent-encoded field-name desynchronization

fast-uri is a dependency-free RFC 3986 URI parser for Node.js, used by Fastify and ajv, that added a mailto scheme parser in version 4.1.3. In versions 4.1.3 and 4.1.4, the mailto parser compares each query field name to the reserved names to, subject, and body while the name is still percent-encoded, and decodes it only when storing it as a generic header, so a percent-encoded spelling of a reserved field name is not recognized as that field at parse time but is re-emitted as the literal field name when the parsed URI is serialized. An application that validates, logs, or displays the recipient list from the first parse and then serializes the URI and sends it can silently gain an attacker-chosen recipient, and the subject and body fields can be smuggled across the same roundtrip. The issue is fixed in fast-uri 4.1.5, and users should upgrade to 4.1.5 or later. As a workaround, do not act on a mailto URI that fast-uri has re-serialized without first decoding and re-validating its recipient, subject, and body fields.
