NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.0, 2.12.7, and 2.11.16, an authenticated user could receive messages on denied subjects when a wildcard subscription overlapped with a configured wildcard deny rule but was not a subset...

SUSE CVE-2026-58253

NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.0, 2.12.7, and 2.11.16, when noauthuser was configured, a parser fast path intended for ordinary client connections could also apply to route or leafnode listeners, allowing an...

The vulnerability of the DefaultHeaderFilterStrategy class in the NATS Java framework by Apache Camel allows a attacker to perform an SSRF attack.

The vulnerability of the DefaultHeaderFilterStrategy class in the NATS Java framework, Apache Camel, is related to insufficient validation of input data when processing parameters such as inFilter, inFilterPattern, and inFilterStartsWith. Exploiting this vulnerability could allow an attacker to...
