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 · unedited
Regex Denial of Service in youtube-regex npm package through version 1.0.5.

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 · moderate confidence

This is a Regular Expression Denial of Service (ReDoS) vulnerability in the youtube-regex npm package. The vulnerable regex pattern can be triggered to cause excessive CPU consumption and service disruption through specially crafted input strings.

MitigationUpdate youtube-regex to a version newer than 1.0.5, or if no fixed version exists, consider alternatives or implement input length/validation limits as a workaround.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check installed youtube-regex version
    Run 'npm list youtube-regex' in your project directory, or inspect package.json dependencies
    Affected if The installed version is 1.0.5 or earlier
  2. Identify all code paths using youtube-regex
    Search your codebase for imports or requires of 'youtube-regex' and review where the returned regex is applied to input
    Affected if The package is imported and its regex is used to validate or parse user-supplied strings
  3. Verify if untrusted input reaches the regex
    Audit the data flow from external sources (HTTP requests, user uploads, API calls) to the youtube-regex function
    Affected if External or untrusted strings are passed to the youtube-regex validation function without length limits
  4. Confirm the vulnerable regex is in use
    Inspect node_modules/youtube-regex/index.js or the installed package source to confirm the regex pattern exists (the flaw is in the package's regex itself, present in versions <=1.0.5)
    Affected if The package version is 1.0.5 or earlier and the regex module is loaded

You are affected if youtube-regex version 1.0.5 or earlier is installed and your application processes untrusted input through the package's regex pattern.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update youtube-regex to a version newer than 1.0.5, or if no fixed version exists, consider alternatives or implement input length/validation limits as a workaround.

Recommended fix Moderate confidence

youtube-regex version greater than 1.0.5 (e.g., latest stable release)

  1. Run `npm list youtube-regex` to identify the current installed version in your project
  2. Run `npm install youtube-regex@latest` or `npm install youtube-regex@>1.0.5` to upgrade to a fixed version
  3. Run `npm audit` to verify the vulnerability is resolved
  4. Commit the updated package-lock.json file
