How to Fix CVE-2022-22138

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

fast-string-search fixed: Latest secure release 
npm install fast-string-search@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 fast-string-search

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-22138, inspect your project dependencies using npm:

npm ls fast-string-search

Analyze the terminal output to locate any version of Fast string search 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 fast-string-search 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-682: Incorrect Calculation, where the product performs a calculation that generates incorrect or unintended results that are later used in security-critical decisions or resource management. In Fast string search, 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

All versions of package fast-string-search are vulnerable to Denial of Service (DoS) when computations are incorrect for non-string inputs. One can cause the V8 to attempt reading from non-permitted locations and cause a segmentation fault due to the violation.
