    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: 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.
