NATS: Message tracing can be redirected to arbitrary subject
Résumé
NATS: Message tracing can be redirected to arbitrary subject
Description d'origine
La description telle que publiée par la source (souvent en anglais).
NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Starting in version 2.11.0 and prior to versions 2.11.15 and 2.12.6, a valid client which uses message tracing headers can indicate that the trace messages can be sent to an arbitrary valid subject, including those to which the client does not have publish permission. The payload is a valid trace message and not chosen by the attacker. Versions 2.11.15 and 2.12.6 contain a fix. No known workarounds are available.
