The record
`POST /{owner}/{repo}/topics` was registered without the sign-in middleware that provides the cross-origin protection, so a request issued by a third-party site was not rejected. A repository administrator who visited a malicious page could have the topics of their repository changed. No other repository settings were reachable through this route.
