GHSA-FW57-JGCH-PGF3 Gitea: ParseAcceptLanguage quadratic-time DoS via Locale middleware on unauthenticated requests

Summary The Locale middleware that runs in front of every unauthenticated request calls golang.org/x/text/language.ParseAcceptLanguage on the raw Accept-Language header without imposing a size or shape filter. The underlying parser has quadratic-time behaviour on long lists of malformed language...

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...
