Gitea SSH Key Parser Denial of Service

Gitea's SSH key ingestion endpoint accepts keys in RFC 4716 SSH2 format and normalises them before storage. The normalisation function contains an ON² string concatenation loop with no input size limit, meaning a single malicious key submission can force the server to perform an amount of work th...
