XSS Vulnerability in Markdown Editor
Blast Radius
inventreeReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Impact
InvenTree uses EasyMDE for displaying markdown text in various places (e.g. for the various "notes" fields associated with various models).
By default, EasyMDE does not sanitize input data, and it is possible for malicious code to be injected into the markdown editor, and executed in the users browser.
Note: This malicious data must be first uploaded to the database by an authorized user, so the risk here is limited to trusted users
Solution
The solution here is two-fold:
- Enable data sanitization for the EasyMDE renderer - #3205
- Enforce cleaning of all data uploaded to the database via the API - #3204 (This will be ready for the 0.8.0 release)
Patches
- The issue is addressed in the 0.8.0 release
- This fix was back-ported to the 0.7.x branch, applied to the 0.7.3 release
Workarounds
There is no workaround for this issue without upgrading InvenTree to the specified version.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for inventree. 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 inventree to 0.7.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-85q9-7467-r53q 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-85q9-7467-r53q 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-85q9-7467-r53q. 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-85q9-7467-r53q in your dependencies?
O3 detects GHSA-85q9-7467-r53q across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
