Advisories for Pypi/Sanic package

Sanic is an opensource python web server/framework. Affected versions of sanic allow access to lateral directories when using app.static if using encoded %2F URLs. Parent directory traversal is not impacted. Users are advised to upgrade. There is no known workaround for this issue.

Sanic 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), your server is prone to crashing on an incoming web request.

Sanic allows reading arbitrary files with directory traversal.
