Local File Inclusion vulnerability in zmarkdown

Description
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for zmarkdown. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update zmarkdown to 10.1.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mq6v-w35g-3c97 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-mq6v-w35g-3c97 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-mq6v-w35g-3c97. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-mq6v-w35g-3c97 in your dependencies?
O3 detects GHSA-mq6v-w35g-3c97 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
