——1FreeScout 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.21h CVE-2026-161516.3 MED

——7A 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.1d CVE-2026-161506.3 MED

——5A vulnerability was found in RobinHerbots Inputmask up to 5.0.9. Affected by this issue is the function extendDefaults/extendDefinitions/extendAliases in the library lib/dependencyLibs/extend.js of the component Internal Deep Merge Helper. 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.1d CVE-2026-543353.7 BAJ

——9Feathersjs 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 5.0.45.23h CVE-2026-488194.8 MED

——8Hey 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 0.97.3.1d CVE-2026-160086.3 MED

——5A 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.4d
