The manipulation of the argument plugin leads to improperly controlled modification of object prototype attributes. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. The identifier of the patch is b4644ab7179700df0607521f61c1ee9b5f78d89d. Applying a patch is the recommended action to fix this issue. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product. | |||||
| CVE-2026-49459 | 1 Cure53 | 1 Dompurify | 2026-10-24 | 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. | |||||
| CVE-2026-53592 | 2026-10-24 | 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-2026-45325 | 2026-10-24 | 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-2026-46681 | 2026-10-24 | 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-2026-16150 | 2026-10-24 | 6.5 MEDIUM | 6.3 MEDIUM | ||
| A 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. | |||||
| CVE-2026-16151 | 2026-10-24 | 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-2026-16008 | 2026-10-24 | 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-2026-48819 | 2026-10-24 | 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-2026-54335 | 2026-10-24 | 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-2026-71437 | 2026-10-24 | N/A | N/A | ||
| Mermaid is a JavaScript tool that uses Markdown-inspired text to create and modify diagrams and charts. From version 11.5.0 until 11.16.1, Mermaid Architecture Diagrams are vulnerable to prototype pollution when a diagram defines a group with an id of __proto__. Because the group id is used directly as an object property key without validation, an attacker who can supply diagram text can pollute Object.prototype, potentially affecting the behavior of the embedding application. This issue is fixed in version 11.16.1. | |||||
| CVE-2026-71438 | 2026-10-24 | N/A | N/A | ||
| Mermaid is a JavaScript tool that uses Markdown-inspired text to create and modify diagrams and charts. Prior to 10.9.8 and 11.16.1, Mermaid's configuration setters (mermaid.initialize, mermaidAPI.setConfig, and mermaidAPI.updateSiteConfig) merge caller-supplied configuration into Mermaid's internal config using the assignWithDepth deep-merge helper, which is vulnerable to prototype pollution. This is only exploitable if an application forwards untrusted data directly into one of these configuration entry points, which is outside their documented usage; diagram-supplied configuration (e.g. %%{init: {}}%% or YAML frontmatter) is not affected. This issue is fixed in versions 10.9.8 and 11.16.1. | |||||
| CVE-2026-73647 | 2026-10-24 | N/A | 5.6 MEDIUM | ||
| Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to 2.22.0, the public extend() utility in ui/src/utils/extend/extend.js recursively copied attacker-controlled object keys during extend(true, target, source) deep merges without rejecting an own __proto__ property. The merge could descend into the prototype object and write attacker-controlled properties to Object.prototype in the same JavaScript process. Applications that passed user-controlled or partially user-controlled objects to extend() could experience logic bypass, unsafe default-option injection, denial of service, or other application-specific impact when polluted properties were later consumed. This issue is fixed in version 2.22.0. | |||||
| CVE-2026-73562 | 2026-10-24 | N/A | 6.5 MEDIUM | ||
| Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. Prior to 6.13.10, 7.8.10, 8.24.1, and 9.7.2, passing a user-controlled update such as MyModel.updateOne(filter, req.body) can exploit Mongoose update casting with a __proto__.x dotted path under $set. Schema.prototype.path and Schema.prototype._getPathType can treat inherited properties of schema.paths and schema.nested as schema types, allowing the casting process to set $fullPath and $parentSchemaDocArray on Object.prototype before throwing. This prototype pollution makes those properties visible on newly created objects and can cause application integrity and availability impacts. This issue is fixed in versions 6.13.10, 7.8.10, 8.24.1, and 9.7.2. | |||||
| CVE-2023-23917 | 1 Rocket.chat | 1 Rocket.chat | 2026-10-24 | N/A | 8.8 HIGH |
| A prototype pollution vulnerability exists in Rocket.Chat server <5.2.0 that could allow an attacker to a RCE under the admin account. Any user can create their own server in your cloud and become an admin so this vulnerability could affect the cloud infrastructure. This attack vector also may increase the impact of XSS to RCE which is dangerous for self-hosted users as well. | |||||
| CVE-2026-65913 | 1 Cure53 | 1 Dompurify | 2026-10-24 | N/A | 6.1 MEDIUM |
| DOMPurify before 3.3.2 contains a prototype pollution vulnerability in USE_PROFILES mode that allows attackers to bypass attribute filtering by polluting Array.prototype properties. Attackers can set Array.prototype properties like onclick to true, causing DOMPurify to accept event handlers as allowlisted attributes and resulting in DOM-based XSS when sanitized markup is rendered. | |||||
| CVE-2026-14893 | 2026-10-23 | N/A | 7.3 HIGH | ||
| IBM Observability with Instana (Agent) Build 1.0.303 through 1.0.320 IBM Instana Node.js tracer component @instana/core version 6.2.1 is vulnerable to prototype pollution through its configuration normalization API. | |||||
| CVE-2026-54737 | 2026-10-23 | N/A | 7.3 HIGH | ||
| @phun-ky/defaults-deep is a library like lodash defaultsDeep with array preservation and no lodash dependency. Prior to 2.0.5, defaultsDeep() recursively merges user-supplied objects without filtering proto, constructor, and prototype, allowing properties to be written to Object.prototype. This issue is fixed in version 2.0.5. | |||||
| CVE-2026-14574 | 1 Eclipse | 1 Theia | 2026-10-23 | N/A | 6.5 MEDIUM |
| In Eclipse Theia versions 0.7.0 and up until including 1.73.1, the `PreferenceUtils.merge` function in `@theia/core` recursively merges preference values without rejecting prototype-related keys (`__proto__`, `constructor`, `prototype`). Because this function is invoked by `PreferenceServiceImpl.doResolve` for every preference resolution across scopes (default, user, workspace, folder), a crafted preference value in a workspace settings file (`.theia/settings.json` or `.vscode/settings.json`) can pollute `Object.prototype` when the user opens the workspace, potentially altering application logic across the Theia process. | |||||
| CVE-2026-48170 | 2026-10-23 | N/A | 9.1 CRITICAL | ||
| `scim-patch`, a library to perform SCIM patch, prior to version 0.9.1 performs prototype pollution when applying a SCIM PATCH operation whose `value` object contains a key like `"__proto__.someProp"`. After one such patch, `Object.prototype.someProp` is set process-wide, affecting every plain object in the Node process. Any service that calls `scimPatch()` on attacker-controlled JSON (i.e. any SCIM endpoint accepting `PATCH` from an external IdP) is exploitable on a stock Node runtime. Version 0.9.1 contains a patch. A workaround is available. Calling `Object.freeze(Object.prototype)` (and the same on `Array.prototype`, `Function.prototype`) at process startup neutralizes this class of bug — assignment to a frozen prototype becomes a silent no-op in sloppy mode or a `TypeError` in strict mode. Node's `--frozen-intrinsics` flag does this for built-ins automatically. | |||||
