How to Fix CVE-2022-25892

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

muhammara fixed: 2.6.1 
npm install muhammara@2.6.1
muhammara fixed: 3.1.1 
npm install muhammara@3.1.1
hummus fixed: 1.0.111 
npm install hummus@1.0.111
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 muhammara

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-25892, inspect your project dependencies using npm:

npm ls muhammara

Analyze the terminal output to locate any version of Muhammara in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.6.1), your application is affected.

Note: The npm ls muhammara 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-690: Unchecked Return Value to NULL Pointer Dereference, where the product does not check for an error after calling a function that can return with a null pointer if the function fails, which leads to a resultant null pointer dereference. In Muhammara, 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.
