GHSA-7f92-rr6w-cq64
Fix: vyperlang/vyper#2379GHSA-7f92-rr6w-cq64 is a security vulnerability in vyper. O3 Security confirms whether GHSA-7f92-rr6w-cq64 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Storage corruption due to variables overwritten by re-entrancy locks
Real-World Exposure
vyperReal-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
Background
When attempting to use the v0.2.14 release, @pandadefi discovered an issue using the @nonreentrant decorator.
Impact
Reentrancy protection storage slots get allocated to the same slots as storage variables, leading to the corruption of storage variables when using the @nonreentrant decorator.
Patches
This issue was fixed in v0.2.15 in #2391, #2379
Workarounds
Don't use the @nonreentrant decorator in these versions.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for vyper. 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 vyper to 0.2.15 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7f92-rr6w-cq64 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-7f92-rr6w-cq64 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-7f92-rr6w-cq64. 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-7f92-rr6w-cq64 in your dependencies?
O3 detects GHSA-7f92-rr6w-cq64 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
