CVE-2026-12143 form-data does not escape CR/LF/quote in multipart field names and filenames (CRLF injection)

form-data is a library for creating readable multipart/form-data streams. In versions through 4.0.5, the field argument to FormDataappend and the filename option are concatenated verbatim into the Content-Disposition header without escaping carriage return CR, line feed LF, or double-quote "...

CVE-2026-46510

form-data-objectizer converts FormData to object. Prior to 1.0.1, form-data-objectizer walks bracket-notation form keys e.g. namesub into nested objects without filtering proto, constructor, or prototype. A single HTTP form field whose name starts with proto... causes the library to mutate...

CVE-2026-45302

parse-nested-form-data is a tiny node module for parsing FormData by name into objects and arrays. Prior to version 1.0.1, parseFormData walks bracket and dot-notation FormData field names into nested objects without filtering reserved property keys. A single FormData field whose name begins with...

CVE-2026-45302

The CVE-2026-45302 entry concerns parse-nested-form-data, a Node.js module that parses FormData field names into nested objects. Before version 1.0.1, parseFormData() could traverse into Object.prototype when a field name begins with proto or contains .proto . mid-path, enabling prototype polluti...

Prototype Pollution

parseFormData is vulnerable to Prototype Pollution. The vulnerability is due to improper filtering of reserved property keys in bracket and dot-notation FormData field parsing, which allows an attacker to modify Object.prototype and pollute the prototype chain of application objects...

NPM: parse-nested-form-data has Prototype Pollution via `__proto__` in FormData field names

NPM: parse-nested-form-data has Prototype Pollution via proto in FormData field names vulnerability discovered by ? in WordPress Npm parse-nested-form-data versions = 1.0.0...

GHSA-XP7R-J8R6-J9H3 parse-nested-form-data has Prototype Pollution via `__proto__` in FormData field names

Summary parseFormData walks bracket and dot-notation FormData field names into nested objects without filtering reserved property keys. A single FormData field whose name begins with proto, or contains .proto. mid-path, causes the parser to traverse onto Object.prototype and assign properties...

GHSA-62HF-57XW-28J9 Axios: unbounded recursion in toFormData causes DoS via deeply nested request data

Summary toFormData recursively walks nested objects with no depth limit, so a deeply nested value passed as request data crashes the Node.js process with a RangeError. Details lib/helpers/toFormData.js:210 defines an inner buildvalue, path that recurses into every object/array child line 225:...

Prototype Pollution

Axios is vulnerable to Prototype Pollution. The vulnerability is due to a gadget in the HTTP adapter lib/adapters/http.js that relies on duck-typed checks for FormData, allowing attacker-controlled properties on Object.prototype e.g., getHeaders to be invoked and inject arbitrary HTTP headers int...

HTTP Response Splitting

Overview axios is a promise-based HTTP client for the browser and Node.js. Affected versions of this package are vulnerable to HTTP Response Splitting via the isFormData and getHeaders handling in the HTTP request path. An attacker can inject arbitrary request headers by supplying a...

CRLF Injection

Overview org.webjars.npm:axios is a promise-based HTTP client for the browser and Node.js. Affected versions of this package are vulnerable to CRLF Injection through the FormDataPart multipart header construction in the form-data streaming helper. An attacker can inject arbitrary multipart header...

CVE-2026-32701 Qwik has array method pollution in FormData processing, allowing type confusion and DoS

Qwik is a performance-focused JavaScript framework. Versions prior to 1.19.2 improperly inferred arrays from dotted form field names during FormData parsing. By submitting mixed array-index and object-property keys for the same path, an attacker could cause user-controlled properties to be writte...

Qwik 安全漏洞

Qwik is a micro-web framework developed by Qwik Dev. Versions of Qwik prior to 1.19.2 contained security vulnerabilities. These vulnerabilities stemmed from improper array inference during FormData parsing from dot-separated form field names, which could lead to request processing failures,...

Prototype Pollution

@trpc/server is vulnerable to Prototype Pollution. The vulnerability is due to improper handling of FormData field names in the formDataToObject function, which allows an attacker to submit specially crafted fields that pollute Object.prototype and potentially cause authorization bypass or denial...

@sveltejs/kit has memory amplification DoS vulnerability in Remote Functions binary form deserializer (application/x-sveltekit-formdata)

Summary The experimental form remote function uses a binary data format containing a representation of submitted form data. A specially-crafted payload can cause the server to allocate a large amount of memory, causing DoS via memory exhaustion. Details When a form is submitted to a remote functi...
