How to Fix CVE-2018-25074

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

skeemas fixed: 1.2.5 
npm install skeemas@1.2.5
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 skeemas

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2018-25074, inspect your project dependencies using npm:

npm ls skeemas

Analyze the terminal output to locate any version of Skeemas in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2.5), your application is affected.

Note: The npm ls skeemas 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 Skeemas, 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

A vulnerability was found in Prestaul skeemas and classified as problematic. This issue affects some unknown processing of the file validators/base.js. The manipulation of the argument uri leads to inefficient regular expression complexity. The name of the patch is 65e94eda62dc8dc148ab3e59aa2ccc086ac448fd. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-218003.
