CVSS v3.1 |
| 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. |
| Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.9, 40.9.2, 41.2.2, and 42.0.0-beta.4, objects copied across the contextBridge boundary from untrusted content could carry an attacker-influenced prototype, enabling prototype-pollution-style attacks against preload code despite context isolation being enabled. Apps are only affected if their preload code accepts object arguments from untrusted content and reads properties from them without own-property checks, while apps that only accept primitive arguments or validate object arguments are not affected. This issue is fixed in 39.8.9, 40.9.2, 41.2.2, and 42.0.0-beta.4. |
| 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. |
| 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__. |
| Deployment of the VPS.org one-click Supabase template deploys a PostgreSQL instance that is published on all interfaces (0.0.0.0:5432) with a default database password set to "postgres". Because Docker installs its own iptables rules, this exposure bypasses a standard host UFW configuration. |
| @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. |
| 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. |
| veraPDF PDF parser is a PDF parser for veraPDF. Prior to 1.30.2 and 1.31.23, veraPDF-parser contains a denial-of-service vulnerability in veraPDF-parser/src/main/java/org/verapdf/pd/font/type1/Type1FontProgram.java and veraPDF-parser/src/main/java/org/verapdf/parser/postscript/PSOperator.java, where a crafted Type 1 font /FontDescriptor /FontFile program can execute unbounded PostScript array allocation, a zero-increment for loop, or self-recursive toExecute user dictionary lookups and exhaust validator memory, CPU, or stack. This issue is fixed in versions 1.30.2 and 1.31.23. |
| veraPDF PDF parser is a PDF parser for veraPDF. Prior to 1.30.2 and 1.31.23, veraPDF-parser contains a denial-of-service vulnerability in veraPDF-parser/src/main/java/org/verapdf/pd/font/cmap/CMapParser.java and veraPDF-parser/src/main/java/org/verapdf/parser/postscript/PSOperator.java, where a crafted Type 0 font /Encoding or /ToUnicode CMap stream can execute unbounded PostScript array allocation or a zero-increment for loop and exhaust validator memory or CPU. This issue is fixed in versions 1.30.2 and 1.31.23. |
| The Boot Dashboard Docker integration in Spring Tools publishes container control ports on all of the host's network interfaces (0.0.0.0) rather than restricting them to loopback.
Affected Spring Products and Versions:
Spring Tools for Eclipse: 5.2.0 and earlier |
| @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. |
| Pivotick used plain JavaScript objects as lookup tables indexed by caller-controlled graph node identifiers in its tree-layout and cycle-detection components.
Node identifiers matching properties inherited from Object.prototype, such as constructor, toString, or __proto__, were not handled as ordinary identifiers. These values could be interpreted as existing inherited properties, resolve to values of an unexpected type, or—in the case of __proto__ assignments—modify the prototype of an internal lookup object.
An attacker who can supply graph data containing crafted node identifiers could consequently cause nodes or edges to be silently omitted, produce incorrect hierarchy levels, bypass or corrupt cycle-detection results, or trigger an exception that interrupts graph processing and rendering. This affects the integrity of graph visualisations and analytics and may cause a client-side denial-of-service condition.
The affected code also failed to safely handle edges whose source node was absent from the supplied node set. Furthermore, calculating the maximum tree depth by spreading all level values into Math.max() could exceed the JavaScript function-argument limit when processing a sufficiently large graph, resulting in an exception and denial of service.
The patch replaces identifier-keyed plain objects with Map instances, ignores invalid edges during tree construction, and calculates the maximum depth iteratively. |
| Deck Mate 1 executes firmware directly from an external EEPROM without verifying authenticity or integrity. An attacker with physical access can replace or reflash the EEPROM to run arbitrary code that persists across reboots. Because this design predates modern secure-boot or signed-update mechanisms, affected systems should be physically protected or retired from service. The vendor has not indicated that firmware updates are available for this legacy model. |
| Deck Mate 2 lacks a verified secure-boot chain and runtime integrity validation for its controller and display modules. Without cryptographic boot verification, an attacker with physical access can modify or replace the bootloader, kernel, or filesystem and gain persistent code execution on reboot. This weakness allows long-term firmware tampering that survives power cycles. The vendor indicates that more recent firmware updates strengthen update-chain integrity and disable physical update ports to mitigate related attack avenues. |
| Using expressions that generate large arrays it is possible to craft a query that creates very large intermediate objects in memory, causing the server to crash with OOM error. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
