GHSA-6r3c-8xf3-ggrr
GHSA-6r3c-8xf3-ggrr is a security vulnerability in django-sendfile2. O3 Security confirms whether GHSA-6r3c-8xf3-ggrr is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Directory traversal outside of SENDFILE_ROOT in django-sendfile2
Blast Radius
django-sendfile2Real-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
django-sendfile2 currently relies on the backend to correctly limit file paths to SENDFILE_ROOT. This is not the case for the simple and development backends, it is also not necessarily the case for any of the other backends either (it's just an assumption that was made by the original author).
This will be fixed in 0.6.0 which is to be released the same day as this advisory is made public.
When upgrading, you will need to make sure SENDFILE_ROOT is set in your settings module if it wasn't already.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for django-sendfile2. 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 django-sendfile2 to 0.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6r3c-8xf3-ggrr 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-6r3c-8xf3-ggrr 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-6r3c-8xf3-ggrr. 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-6r3c-8xf3-ggrr in your dependencies?
O3 detects GHSA-6r3c-8xf3-ggrr across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
