CVE-2025-49223
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedbillboard.js before 3.15.1 was discovered to contain a prototype pollution via the function generate, which could allow attackers to execute arbitrary code or cause a Denial of Service (DoS) via injecting arbitrary properties.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidencebillboard.js before 3.15.1 is vulnerable to prototype pollution via the generate function, allowing attackers to inject arbitrary properties into JavaScript object prototypes, which can lead to arbitrary code execution or denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify billboard.js installationCheck your project's package.json for billboard.js in dependencies, or run 'npm list billboard.js' to see the installed versionAffected if The installed version is any version before 3.15.1 (e.g., 3.15.0, 3.14.0, etc.)
-
Locate the billboard.js library fileFind the billboard.js file in your node_modules or static assets (typically in node_modules/billboard.js/dist/ or similar path)Affected if The library file exists in your environment
-
Verify the generate function usageSearch your codebase for calls to the 'generate' function from billboard.js (e.g., search for 'bb.generate' or 'billboard.generate')Affected if Your code calls the generate function and the billboard.js version is below 3.15.1
-
Check for prototype pollution sinksReview code that passes user-controlled input to the generate function's options parameterAffected if User input flows into the options object passed to generate without sanitization, and the vulnerable version is in use
You are affected if billboard.js version is below 3.15.1 and your application uses the generate function with potentially untrusted input.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped3.15.1
Upgrade billboard.js to version 3.15.1 or later to receive the patch for this prototype pollution vulnerability.
billboard.js 3.15.1
- Check current billboard.js version by running `npm list billboard.js` or checking package.json
- Update billboard.js to version 3.15.1 or later by running `npm install billboard.js@^3.15.1` or `yarn add billboard.js@^3.15.1`
- Verify the update was successful by running `npm list billboard.js`
- Test the application to ensure the `generate` function works correctly and no prototype pollution can occur
- Consider updating to the latest stable version (3.15.1 or higher) to get all security patches
