@perfood/couch-auth fixed: Latest secure release 
npm install @perfood/couch-auth@Latest secure release
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 @perfood/couch-auth

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-70949, inspect your project dependencies using npm:

npm ls @perfood/couch-auth

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

Note: The npm ls @perfood/couch-auth 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-208: Observable Timing Discrepancy, where two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product, such as whether a particular operation was successful or not. In @perfood/couch auth, 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.

Source Advisory Statement
