npm install zmarkdown@10.1.3
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 zmarkdown

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-mq6v-w35g-3c97, inspect your project dependencies using npm:

npm ls zmarkdown

Analyze the terminal output to locate any version of Zmarkdown in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 10.1.3), your application is affected.

Note: The npm ls zmarkdown 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 General Security Weakness. In Zmarkdown, 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 A minor Local File Inclusion vulnerability has been found in `zmarkdown`, which allowed for images with a known path on the host machine to be included inside a LaTeX document. To prevent it, a new option has been created that allow to replace invalid paths with a default image instead of linking the image on the host directly. `zmarkdown` has been updated to make this setting the default. Every user of `zmarkdown` is likely impacted, except if disabling LaTeX generation or images download. Here is an example of including an image from an invalid path: ```markdown ![](/tmp/img.png) ``` Will effectively redownload and include the image found at `/tmp/img.png`. ### Patches The vulnerability has been patched in version 10.1.3. If impacted, you should update to this version as soon as possible. ### Workarounds Disable images downloading, or sanitize paths. ### For more information If you have any questions or comments about this advisory, open an issue in [ZMarkdown](https://github.com/zestedesavoir/zmarkdown/issues).
