EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
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 allows unrestricted upload of files as attachments to various database fields. Potentially dangerous files (such as HTML files containing malicious javascript) can be uploaded, and (when opened by the user) run the malicious code directly in the users browser.
Note that the upload of malicious files must be performed by an authenticated user account
Solution
The solution for this vulnerability is to ensure that attachment files are downloaded to the local machine before opening, rather than opening the file in the current browser context.
Patches
- The issue is addressed in the upcoming 0.8.0 release
- This fix will also be back-ported to the 0.7.x branch, applied to the 0.7.2 release
Workarounds
Users can alleviate risk of opening malicious files by right-clicking on the attachment link and selecting "Save link as"
This minimizes risk (e.g. of XSS attacks) by opening the HTML file from the users computer

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 0.7.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-fr2w-mp56-g4xp 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-fr2w-mp56-g4xp 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-fr2w-mp56-g4xp. 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-fr2w-mp56-g4xp in your dependencies?
O3 detects GHSA-fr2w-mp56-g4xp across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
