GHSA-7p79-6x2v-5h88 is a security vulnerability in sanic. A fix is available for sanic — see the affected versions and patch details below.
Server crash if running Python 3.10 w/ Sanic 20.12
Real-World Exposure
sanicReal-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
!!! ONLY APPLIES TO VERSIONS PRIOR TO Sanic v20.12 WHEN USING Python 3.10 !!!
Sanic v20.12 officially supports Python versions 3.6, 3.7, 3.8, and 3.9. However, if you accidentally run it with version 3.10 (which is not supported by Sanic 20.12), your server is prone to crashing on an incoming web request.
Impact
Anyone running Sanic server between 0.1.7 and 20.12 using Python 3.10.
Patches
Workarounds
Use a supported version of Python (v3.6 - v3.9)

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sanic, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update sanic to 20.12.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7p79-6x2v-5h88 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-7p79-6x2v-5h88 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-7p79-6x2v-5h88. 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-7p79-6x2v-5h88 in your dependencies?
O3 Security finds GHSA-7p79-6x2v-5h88 across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
