| CVE-2026-59876 | 1 Protobuf | 1 Protobuf | 2026-07-10 | 4.8 Medium |
| protobufjs compiles protobuf definitions into JavaScript (JS) functions. From 8.2.0 until 8.6.5, the protobufjs Text Format extension parsed string-keyed map entries using ordinary property assignment, allowing a map entry with key __proto__ to change the prototype of the returned map object instead of creating an own map entry in protobufjs/ext/textformat. This issue is fixed in version 8.6.5. | ||||
| CVE-2026-59206 | 1 N8n | 1 N8n | 2026-07-10 | N/A |
| n8n is an open source workflow automation platform. Prior to 1.123.61, 2.27.4, and, 2.28.1, an authenticated user with the default workflow:create permission could pollute Object.prototype through a crafted workflow saved, updated, or imported via the workflow API, allowing unauthenticated requests to be treated as a privileged user and exposing user and project listing endpoints. This issue is fixed in versions 1.123.61, 2.27.4, and 2.28.1. | ||||
| CVE-2026-15195 | 1 Apidevtools | 1 Json-schema-ref-parser | 2026-07-09 | 6.3 Medium |
| A weakness has been identified in apidevtools json-schema-ref-parser up to 15.3.5. This impacts the function Refs.set/Pointer.set in the library lib/pointer.ts.

| CVE-2026-57439 | 1 Gchq | 1 Cyberchef | 2026-07-08 | 5 Medium |
| CyberChef is a web app for encryption, encoding, compression, and data analysis. Prior to 11.2.0, the Series Chart operation accepts __proto__ as a key while parsing user-supplied CSV, allowing prototype pollution that can be chained with operations such as Parse UDP to inject malicious JavaScript into HTML output. This issue is fixed in version 11.2.0. | ||||
| CVE-2026-55886 | 1 Xdan | 1 Jodit | 2026-07-06 | N/A |
| Jodit Editor is a WYSIWYG editor with written in pure TypeScript file and image editing capabilities. Versions prior to 4.12.26 are vulnerable to Prototype Pollution through Jodit.modules.Helpers.set(chain, value, obj), which walks the dot-separated chain, creating and following each path segment without filtering prototype-mutating keys. A chain that begins with (or contains) __proto__, constructor, or prototype lets the final assignment reach and mutate Object.prototype. Applications that pass a user-controlled or partially user-controlled key path into Jodit.modules.Helpers.set() could be vulnerable, causing unexpected property injection, logic bypass, denial of service, or secondary security issues. This issue has been fixed in version 4.12.26. | ||||
| CVE-2026-54756 | 1 Xdan | 1 Jodit | 2026-07-06 | N/A |
| Jodit Editor is a WYSIWYG editor with written in pure TypeScript file and image editing capabilities. In versions prior to 4.12.18, Jodit.configure(options) — and the internal ConfigMerge / ConfigProto helpers — merged user-supplied options into the editor configuration without filtering prototype-mutating keys, potentially causing a Prototype Pollution vulnerability. A payload nested under an existing plain-object option such as controls could reach and mutate Object.prototype. Applications that pass user-controlled or partially user-controlled configuration into Jodit.configure() may be vulnerable. This issue was fixed in version 4.12.18. | ||||
| CVE-2026-8657 | 1 Benjamine | 1 Jsondiffpatch | 2026-07-05 | 8.2 High |
| Versions of the package jsondiffpatch before 0.7.6 are vulnerable to Prototype Pollution via the jsondiffpatch.patch() and jsondiffpatch/formatters/jsonpatch.patch() APIs. An attacker can perform prototype pollution by supplying crafted delta or JSON Patch documents, as attacker-controlled property names and path segments are used to traverse and modify objects without restricting access to special properties like __proto__ or constructor.prototype, allowing modification of Object.prototype. | ||||
| CVE-2026-54306 | 1 N8n | 1 N8n | 2026-06-26 | N/A |
| n8n is an open source workflow automation platform. Prior to 2.25.7 and 2.26.2, a prototype pollution vulnerability allowed a crafted public webhook payload to inject attacker-controlled fields into workflow data during internal object copying. These fields could be surfaced and consumed as normal values by downstream built-in nodes. Where a workflow combines a public webhook with action nodes that consume the resulting fields, an attacker could cause the workflow to act as a confused deputy — targeting unintended records or issuing outbound requests using the workflow owner's configured credentials. This vulnerability is fixed in 2.25.7 and 2.26.2. | ||||
| CVE-2026-57926 | 1 Jetbrains | 1 Youtrack | 2026-06-26 | 2.6 Low |
| In JetBrains YouTrack before 2026.2.16593 the websandbox bridge was vulnerable to a prototype pollution attack | ||||
| CVE-2026-54639 | 1 Style-dictionary | 1 Style-dictionary | 2026-06-24 | 8.8 High |
| Style Dictionary, a build system for creating cross-platform styles, has a prototype pollution vulnerability starting in version 4.3.0 and prior to version 5.4.4. Impact users have: direct usage of `convertTokenData(tokens, { output: 'object' });`; indirect usage, via using Expand API; and/or indirect usage via SD's transform lifecycle. Impact is high for this when style-dictionary is used as an integration in a NodeJS server application. Impact is moderate for when style-dictionary is used as an integration in a Web application. Impact is low for most common cases where the user of style-dictionary also maintains the tokens, and access is limited via read/write access to the repository/workflows where it is used. A patch has been published in version `5.4.4`. The only known workaround is to sanitize token data first. Whether using DTCG format or old Style Dictionary format, check the token data object recursively for any object keys that include `__proto__`. | ||||
| CVE-2026-54312 | 1 N8n | 1 N8n | 2026-06-24 | N/A |
| n8n is an open source workflow automation platform. Prior to 2.24.0, an authenticated user with permission to create or modify workflows could achieve global prototype pollution via the Microsoft SQL node by supplying a crafted value as the table parameter. This pollutes Object.prototype process-wide for the lifetime of the n8n server process, causing application-wide validation failures and rendering the n8n instance completely non-functional until restarted. This vulnerability is fixed in 2.24.0. | ||||
| CVE-2026-44789 | 1 N8n | 1 N8n | 2026-06-24 | N/A |
| n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an authenticated user with permission to create or modify workflows could achieve global prototype pollution via an unvalidated pagination parameter in the HTTP Request node. Combined with other techniques this could lead to RCE on the instance. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7. | ||||
| CVE-2026-44791 | 1 N8n | 1 N8n | 2026-06-24 | N/A |
| n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an authenticated user with permission to create or modify workflows could bypass the patch for CVE-2026-42232 in the XML node. When combined with other nodes, this could lead to RCE on the n8n host. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7. | ||||
| CVE-2026-55388 | 1 Piscinajs | 1 Piscina | 2026-06-23 | 8.1 High |
| piscina is a node.js worker pool implementation. Prior to 6.0.0-rc.2, 5.2.0, and 4.9.3, piscina's constructor and run() paths read the filename option via plain member access. Both reads fall through the prototype chain when the caller's options object doesn't have filename as an own property. When Object.prototype.filename is polluted upstream the inherited value flows to worker_threads.Worker import and the attacker's .mjs runs in the worker. This vulnerability is fixed in 6.0.0-rc.2, 5.2.0, and 4.9.3. | ||||
| CVE-2026-49252 | 1 Deepstreamio | 1 Deepstream.io | 2026-06-22 | 9.9 Critical |
| deepstream is a server that allows clients and backend services to sync data, send messages and make rpcs at scale. Versions prior to 10.0.5 are vulnerable to Prototype Pollution. Exploitation can lead to potential privilege escalation from any authenticated user with write permission to any record. This issue has been fixed in version 10.0.5. | ||||
| CVE-2026-53676 | 1 Thingsboard | 1 Thingsboard | 2026-06-18 | N/A |
| ThingsBoard contains a prototype pollution vulnerability which may lead to arbitrary code execution within a sandboxed context by a user who can log in to the affected product with the tenant administrator privilege (TENANT_ADMIN). | ||||
