CVE-2026-49098

A flaw was found in the Apache Camel Kafka Component. A remote attacker can exploit an improper input validation vulnerability by manipulating specific Kafka headers, such as kafka.OVERRIDETOPIC, when an HTTP consumer bridges into a Kafka producer. This allows the attacker to redirect messages to...

nats-server: NATS Server: Information disclosure due to inconsistent MQTT topic rechecking

A flaw was found in NATS Server. This vulnerability allows for unauthorized information disclosure where MQTT messages, intended to be denied based on subscription rules, are still delivered to subscribers. This occurs because the server's delivery paths do not consistently recheck the original...

rabbitmq: RabbitMQ: Authorization bypass allows unauthorized topic writes and binds during metadata-store failures

A flaw was found in RabbitMQ, a messaging and streaming broker. During metadata-store failures, the topic authorization mechanism can incorrectly allow restricted topic writes and binds. This occurs because permission lookup errors from Khepri are treated as an 'allow' condition by the internal...
