CVE-2026-46509

deepobj provides get, set, delete deep objects in javascript. Prior to 1.0.3, prototype pollution is possible when property paths contain proto/constructor/prototype. The property path must not be exposed as user input. This vulnerability is fixed in 1.0.3...

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...

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-M2HG-WJQ3-28WQ form-data-objectizer: Prototype pollution in form-data-objectizer via bracket-notation form keys

Summary 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 Object.prototype, which is a prototype pollution primitive of th...

CVE-2026-44292 protobufjs: Prototype injection in generated message constructors

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.5.6 and 8.0.2, protobufjs generated message constructors copied enumerable properties from a provided properties object without filtering the proto key. If an application constructed a message from an...

protobuf.js 安全漏洞

protobuf.js is a pure JavaScript implementation of the protobuf.js project, open source. It provides a protocol buffer implementation that supports Node.js and browsers with TypeScript. It’s easy to use, extremely fast, and can be used out of the box through.proto files. Versions prior to 7.5.6 a...

Prototype Pollution

Overview protobufjs is a protocol buffer for JavaScript & TypeScript. Affected versions of this package are vulnerable to Prototype Pollution in the process of copying enumerable properties from a user-supplied object to a generated message instance without filtering the proto property. An attack...

CVE-2026-6621 1024bit extend-deep index.js prototype pollution

A vulnerability was determined in 1024bit extend-deep up to 0.1.6. The impacted element is an unknown function of the file index.js. This manipulation of the argument proto causes improperly controlled modification of object prototype attributes. Remote exploitation of the attack is possible. The...

extend-deep 安全漏洞

extend-deep is a JavaScript library developed by Hangga, designed for deeply recursive object merging. Versions of extend-deep 0.1.6 and earlier contained a security vulnerability, which stemmed from improper handling of the proto parameter in the index.js file. This vulnerability could lead to...

Node.js: Node.js: Denial of Service due to crafted HTTP `__proto__` header

A flaw was found in Node.js. A remote attacker can exploit this vulnerability by sending a specially crafted HTTP request that includes a header named proto. When a Node.js application processes this request and attempts to access distinct headers, it encounters an unhandled error, leading to an...

SUSE-SU-2026:21181-1 Security update for nodejs24

This update for nodejs24 fixes the following issues: Update to version 24.14.1. Security issues fixed: - CVE-2026-21717: trivially predictable hash collisions due to flaw in V8's string hashing mechanism allows for performance degradation via a crafted request bsc1260494. - CVE-2026-21716:...

CVE-2026-35209 defu: Prototype pollution via `__proto__` key in defaults argument

defu is software that allows uers to assign default properties recursively. Prior to version 6.1.5, applications that pass unsanitized user input e.g. parsed JSON request bodies, database records, or config files from untrusted sources as the first argument to defu are vulnerable to prototype...

CVE-2026-35209

CVE-2026-35209 affects defu, a recursive defaults merger. Before v6.1.5, the vulnerable code path uses Object.assign({}, defaults) in _defu, which can trigger the proto setter and pollute the Object prototype, allowing attacker-controlled values to appear in the final result. The vulnerability ar...

BIT-NODE-2026-21710

A flaw in Node.js HTTP request handling causes an uncaught TypeError when a request is received with a header named proto and the application accesses req.headersDistinct. When this occurs, dest"proto" resolves to Object.prototype rather than undefined, causing .push to be called on a non-array...

GHSA-W48F-FWG7-WW6P @stablelib/cbor: Prototype poisoning via `__proto__` map keys in CBOR decoding

Summary @stablelib/cbor decodes CBOR maps into ordinary JavaScript objects and assigns attacker-controlled keys directly onto those objects. A CBOR map key named proto therefore changes the prototype of the decoded object instead of becoming an ordinary data property. Details The decoder builds m...

Prototype Pollution

Overview @stablelib/cbor is a CBOR encoder and decoder Affected versions of this package are vulnerable to Prototype Pollution via the CBOR decoding process. An attacker can manipulate the prototype of decoded objects by supplying specially crafted map keys, such as proto, which can lead to...
