How to Fix CVE-2025-2792

To remediate this vulnerability, upgrade all affected @mozilla/readability dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@mozilla/readability fixed: 0.6.0 
npm install @mozilla/readability@0.6.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @mozilla/readability

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-2792, inspect your project dependencies using npm:

npm ls @mozilla/readability

Analyze the terminal output to locate any version of @mozilla/readability in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.6.0), your application is affected.

Note: The npm ls @mozilla/readability command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1333: Inefficient Regular Expression Complexity, where the product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential. In @mozilla/readability, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.
