GHSA-r2h2-g46h-8mx8
Fix: pretix/pretix@4b56518GHSA-r2h2-g46h-8mx8 is a CWE-639 vulnerability in pretix. O3 Security confirms whether GHSA-r2h2-g46h-8mx8 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-World Exposure
pretix🐍pretix🐍pretixReal-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
Multiple API endpoints allowed access to sensitive files from other users by knowing the UUID of the file that were not intended to be accessible by UUID only.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐍PyPI | pretix | ≥ 2025.10.0&&< 2025.10.1 | 2025.10.1 |
| 🐍PyPI | pretix | ≥ 2025.9.0&&< 2025.9.3 | 2025.9.3 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pretix. 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 pretix to 2025.10.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r2h2-g46h-8mx8 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-r2h2-g46h-8mx8 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-r2h2-g46h-8mx8. 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-r2h2-g46h-8mx8 in your dependencies?
O3 detects GHSA-r2h2-g46h-8mx8 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
