How to Fix CVE-2015-10005

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

markdown-it fixed: 3.0.0 
npm install markdown-it@3.0.0
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 markdown-it

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2015-10005, inspect your project dependencies using npm:

npm ls markdown-it

Analyze the terminal output to locate any version of Markdown it in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.0), your application is affected.

Note: The npm ls markdown-it 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 Markdown it, 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 markdown-it up to 2.x. It has been classified as problematic. Affected is an unknown function of the file `lib/common/html_re.js`. The manipulation leads to inefficient regular expression complexity. Upgrading to version 3.0.0 is able to address this issue. The name of the patch is 89c8620157d6e38f9872811620d25138fc9d1b0d. It is recommended to upgrade the affected component. The identifier of this vulnerability is VDB-216852.
