    Summary: Traefik may display authorization header in the debug logs

    Details: ### Impact There is a potential vulnerability in Traefik displaying the Authorization header in its debug logs. Traefik uses [oxy](https://github.com/vulcand/oxy) to provide the following features: - Round Robin: https://doc.traefik.io/traefik/routing/services/#weighted-round-robin-service - Buffering: https://doc.traefik.io/traefik/middlewares/http/buffering/ - Circuit Breaker: https://doc.traefik.io/traefik/middlewares/http/circuitbreaker/ - In-Flight Requests: https://doc.traefik.io/traefik/middlewares/http/inflightreq/ In such cases, if the log level is set to DEBUG, the credentials provided using the Authorization header are displayed in the debug logs: ``` level=debug msg="vulcand/oxy/roundrobin/rr: completed ServeHttp on request" Request="{\\"Method\\":\\"POST\\",\\"URL\\":{\\"Scheme\\":\\"\\",\\"Opaque\\":\\"\\",\\"User\\":null,\\"Host\\":\\"\\",\\"Path\\":\\"/<redacted>/<redacted>\\",\\"RawPath\\":\\"\\",\\"ForceQuery\\":false,\\"RawQuery\\":\\"\\",\\"Fragment\\":\\"\\",\\"RawFragment\\":\\"\\"},\\"Proto\\":\\"HTTP/2.0\\",\\"ProtoMajor\\":2,\\"ProtoMinor\\":0,\\"Header\\":{\\"Authorization\\":[\\"Bearer <token value was here>\\"],\\"Content-Type\\":[\\"application/grpc\\"],\\"Grpc-Accept-Encoding\\":[\\"gzip\\"],\\"Grpc-Timeout\\":[\\"29999886u\\"],\\"Te\\":[\\"trailers\\"],\\"User-Agent\\":[\\"<redacted>\\"],<remainder of log message removed> ``` ### Patches https://github.com/traefik/traefik/pull/9574 https://github.com/traefik/traefik/releases/tag/v2.9.6 ### Workarounds Set the log level to `INFO`, `WARN`, or `ERROR`. ### For more information If you have any questions or comments about this advisory, please [open an issue](https://github.com/traefik/traefik/issues).
