How to Fix CVE-2023-23925

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

switcher-client fixed: 3.1.4 
npm install switcher-client@3.1.4
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 switcher-client

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-23925, inspect your project dependencies using npm:

npm ls switcher-client

Analyze the terminal output to locate any version of Switcher client in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.1.4), your application is affected.

Note: The npm ls switcher-client 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Switcher client, 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

### Impact Unsanitized input flows into Strategy match operation (EXIST), where it is used to build a regular expression. This may result in a Regular expression Denial of Service attack (reDOS). ### Patches Patched in 3.1.4 ### Workarounds Avoid using Strategy settings that use REGEX in conjunction with EXIST and NOT_EXIST operations.
