| CVE-2026-46681 | 2026-07-21 | N/A | N/A | ||
| @nevware21/ts-utils is a comprehensive TypeScript/JavaScript utility library. Prior to version 0.14.0, the _copyProps function in lib/src/object/copy.ts uses for...in to iterate over source object properties without an Object.hasOwnProperty check, and does not filter dangerous keys (__proto__, constructor, prototype). This allows an attacker to pollute the prototype chain of all objects in the application. Version 0.14.0 patches the issue. | |||||
| CVE-2026-44495 | 2026-07-21 | N/A | 7.0 HIGH | ||
| Axios is a promise based HTTP client for the browser and Node.js. From 0.19.0 to before 0.31.1 and 1.15.2, Axios contains prototype-pollution gadgets in request config processing. If another vulnerability in the same JavaScript process has already polluted Object.prototype.transformResponse, affected Axios versions may treat that inherited value as request configuration or as an option validator. Axios does not itself create the prototype pollution. Exploitability requires a separate prototype-pollution vulnerability or equivalent attacker control over Object.prototype before Axios creates a request. This vulnerability is fixed in 0.31.1 and 1.15.2. | |||||
| CVE-2026-44494 | 1 Axios | 1 Axios | 2026-07-21 | N/A | 8.7 HIGH |
| Axios is a promise based HTTP client for the browser and Node.js. From 1.0.0 to before 1.16.0, the Axios library is vulnerable to a Prototype Pollution "Gadget" attack that allows any Object.prototype pollution in the application's dependency tree to be escalated into a full Man-in-the-Middle (MITM) attack — intercepting, reading, and modifying all HTTP traffic including authentication credentials. The HTTP adapter at lib/adapters/http.js:670 reads config.proxy via standard property access, which traverses the prototype chain. Because proxy is not present in Axios defaults, the merged config object has no own proxy property, making it trivially injectable via prototype pollution. Once injected, setProxy() routes all HTTP requests through the attacker's proxy server. This vulnerability is fixed in 1.16.0. | |||||
| CVE-2026-42264 | 1 Axios | 1 Axios | 2026-07-21 | N/A | 7.4 HIGH |
| Axios is a promise based HTTP client for the browser and Node.js. From version 1.0.0 to before version 1.15.2, fFive config properties (auth, baseURL, socketPath, beforeRedirect, and insecureHTTPParser) in the HTTP adapter are read via direct property access without hasOwnProperty guards, making them exploitable as prototype pollution gadgets. When Object.prototype is polluted by another dependency in the same process, axios silently picks up these polluted values on every outbound HTTP request. This issue has been patched in version 1.15.2. | |||||
| CVE-2026-42044 | 1 Axios | 1 Axios | 2026-07-21 | N/A | 6.5 MEDIUM |
| Axios is a promise based HTTP client for the browser and Node.js. From 1.0.0 to before 1.15.2, he Axios library is vulnerable to a Prototype Pollution "Gadget" attack that allows any Object.prototype pollution in the application's dependency tree to be escalated into surgical, invisible modification of all JSON API responses — including privilege escalation, balance manipulation, and authorization bypass. The default transformResponse function at lib/defaults/index.js:124 calls JSON.parse(data, this.parseReviver), where this is the merged config object. Because parseReviver is not present in Axios defaults, not validated by assertOptions, and not subject to any constraints, a polluted Object.prototype.parseReviver function is called for every key-value pair in every JSON response, allowing the attacker to selectively modify individual values while leaving the rest of the response intact. This vulnerability is fixed in 1.15.2. | |||||
| CVE-2026-42041 | 1 Axios | 1 Axios | 2026-07-21 | N/A | 4.8 MEDIUM |
| Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, the Axios library is vulnerable to a Prototype Pollution "Gadget" attack that allows any Object.prototype pollution to silently suppress all HTTP error responses (401, 403, 500, etc.), causing them to be treated as successful responses. This completely bypasses application-level authentication and error handling. The root cause is that validateStatus is the only config property using the mergeDirectKeys merge strategy, which uses JavaScript's in operator — an operator that inherently traverses the prototype chain. When Object.prototype.validateStatus is polluted with () => true, all HTTP status codes are accepted as success. This vulnerability is fixed in 1.15.1 and 0.31.1. | |||||
| CVE-2026-42033 | 1 Axios | 1 Axios | 2026-07-21 | N/A | 7.4 HIGH |
| Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, when Object.prototype has been polluted by any co-dependency with keys that axios reads without a hasOwnProperty guard, an attacker can (a) silently intercept and modify every JSON response before the application sees it, or (b) fully hijack the underlying HTTP transport, gaining access to request credentials, headers, and body. The precondition is prototype pollution from a separate source in the same process. This vulnerability is fixed in 1.15.1 and 0.31.1. | |||||
| CVE-2026-29063 | 1 Immutable-js | 1 Immutable | 2026-07-21 | N/A | 9.8 CRITICAL |
| Immutable.js provides many Persistent Immutable data structures. Prior to versions 3.8.3, 4.3.7, and 5.1.5, Prototype Pollution is possible in immutable via the mergeDeep(), mergeDeepWith(), merge(), Map.toJS(), and Map.toObject() APIs. This issue has been patched in versions 3.8.3, 4.3.7, and 5.1.5. | |||||
| CVE-2025-13465 | 1 Lodash | 1 Lodash | 2026-07-21 | N/A | 5.3 MEDIUM |
| Lodash versions 4.0.0 through 4.17.22 are vulnerable to prototype pollution in the _.unset and _.omit functions. An attacker can pass crafted paths which cause Lodash to delete methods from global prototypes. The issue permits deletion of properties but does not allow overwriting their original behavior. This issue is patched on 4.17.23 | |||||
| CVE-2026-46510 | 2026-07-21 | N/A | 8.2 HIGH | ||
| form-data-objectizer converts FormData to object. Prior to 1.0.1, form-data-objectizer walks bracket-notation form keys (e.g. name[sub]) 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 the entire Node.js process. This vulnerability is fixed in 1.0.1. | |||||
| CVE-2026-16266 | 2026-07-21 | N/A | 4.0 MEDIUM | ||
| Versions of the package mongo-object before 3.0.3 are vulnerable to Prototype Pollution via the expandKey() function in util.js. An attacker can modify the JavaScript prototype chain by supplying a crafted property path containing special keys such as __proto__. | |||||
| CVE-2026-53592 | 2026-07-20 | N/A | 4.6 MEDIUM | ||
| FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. A Prototype Pollution condition in the `getQueryParam` function `/public/js/main.js` and was addressed in version 1.8.139 by blocking URL query keys matching the pattern `__proto__`. However, this mitigation is incomplete: it only filters top-level `__proto__` keys and fails to sanitize nested forms such as `b[__proto__][polluted]=PWNED`. As a result, an attacker-controlled URL query string can still write into `Object.prototype` on any page that loads `main.js`. Version 1.8.223 contains a updated fix. | |||||
| CVE-2026-54335 | 2026-07-20 | N/A | 3.7 LOW | ||
| Feathersjs is a framework for creating web APIs and real-time applications with TypeScript or JavaScript. In 5.0.44 and earlier, the _.merge(target, source) utility exported by @feathersjs/commons recursively merges source into target by iterating Object.keys(source). When source was produced by JSON.parse and contains a __proto__, constructor, or prototype key, that key is returned as an own-enumerable property; the recursive merge then resolves target['__proto__'] to Object.prototype and writes attacker-supplied properties onto it, polluting the prototype for all plain objects in the process for the lifetime of the Node process. This issue is fixed in version 5.0.45. | |||||
| CVE-2026-48819 | 2026-07-20 | N/A | 4.8 MEDIUM | ||
| Hey API is an ecosystem for turning API specifications into production-ready code. Prior to 0.97.3, dist/clients/core/params.ts ships a runtime template copied into generated SDKs as params.gen.ts, and buildClientParams writes unknown slot-prefixed keys such as $body_, $headers_, $path_, and $query_ directly to the corresponding slot, allowing $query___proto__ alongside a legitimate q field to set params.query through params["query"]["__proto__"] = value, call Object.setPrototypeOf(params.query, value), and expose inherited attacker-controlled keys during for..in iteration. This issue is fixed in version 0.97.3. | |||||
| CVE-2026-16150 | 2026-07-20 | 6.5 MEDIUM | 6.3 MEDIUM | ||

The manipulation results in improperly controlled modification of object prototype attributes. The attack may be performed from remote. The project was informed of the problem early through an issue report but has not responded yet. | |||||
| CVE-2026-16151 | 2026-07-20 | 6.5 MEDIUM | 6.3 MEDIUM | ||
| A vulnerability has been found in CartoDB carto-api-client 0.5.29. This impacts the function addFilter of the file src/filters.ts. Such manipulation of the argument column leads to improperly controlled modification of object prototype attributes. The attack can be executed remotely. The project was informed of the problem early through an issue report but has not responded yet. | |||||
| CVE-2026-45325 | 2026-07-17 | N/A | 8.2 HIGH | ||
| Gestor de Oferta is a web application for managing mobility service offerings. Prior to 20260509.0340.15, @tmlmobilidade/utils has a prototype pollution vulnerability in setValueAtPath() in packages/utils/src/generic/value-at-path.ts because unsafe path segments are not blocked. This issue is fixed in version 20260509.0340.15. | |||||
| CVE-2026-16008 | 2026-07-17 | 6.5 MEDIUM | 6.3 MEDIUM | ||
| A security vulnerability has been detected in sagold json-schema-library 11.5.0/11.5.1. This impacts the function parsePropertyDependencies of the file src/keywords/propertyDependencies.ts. The manipulation leads to improperly controlled modification of object prototype attributes. The attack can be initiated remotely. Upgrading to version 11.6.0 will fix this issue. The identifier of the patch is 432287ee6f68a02ce6f015354618486ec427a32d. It is advisable to upgrade the affected component. | |||||
| CVE-2026-48795 | 2026-07-16 | N/A | 8.6 HIGH | ||
| AdonisJS is a TypeScript-first web framework. From 10.1.3 until 10.1.5 and 11.0.3, AdonisJS @adonisjs/bodyparser incompletely fixed CVE-2026-25754 because nested multipart field payloads such as user.__proto__.polluted and constructor.prototype still caused lodash _.set() via @poppinss/utils to create plain intermediate objects and pollute Object.prototype. This issue is fixed in versions 10.1.5 and 11.0.3. | |||||
| CVE-2026-49459 | 2026-07-15 | N/A | 6.1 MEDIUM | ||
| DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG. Prior to 3.4.6, DOMPurify.sanitize(root, { IN_PLACE: true }) could preserve event-handler attributes on an attacker-controlled <form> root when a descendant name clobbered properties checked by _isClobbered, because _forceRemove no-opped on the parent-less root and _sanitizeAttributes returned early. This issue is fixed in version 3.4.6. | |||||
