CVE-2026-86792: Apache Airflow Apache Kafka provider: Connection-editor remote code execution on the Scheduler via Kafka connection callback configuration

Apache Airflow Kafka provider 1.15.0 before 2.0.0 resolves unvalidated dotted-path strings into Python callables, enabling Scheduler RCE.

CVE-2026-86792 (moderate) affects apache-airflow-providers-apache-kafka versions 1.15.0 before 2.0.0. Dotted-path strings in a Kafka connection's extra field are resolved into Python callables via import_string with no allowlist, then invoked by the confluent-kafka client. This allows someone with Kafka connection configuration access to achieve remote code execution on the Airflow Scheduler; upgrading to 2.0.0 resolves it.

A Feature-Rich Embedded NIDS with eBPF/XDP: Detector and Architecture Trade-offs

eBPF/XDP-based NIDS with Isolation Forest reaches 0.965 live F1 on DDoS replay; gRPC microservices match monolithic accuracy within 2ms overhead.

The paper presents a DDoS-focused network intrusion detection system for transport networks built with Ericsson, combining a statistical baseline with an Isolation Forest trained on flow features from GoFlowMeter, an open-source Go implementation of CICFlowMeter, plus eBPF/XDP kernel-level traffic filtering. On a Raspberry Pi 5 testbed replaying CIC-DDoS2019 as real traffic, the Isolation Forest achieves 0.965 recall/F1 live in the monolithic variant, catching low-volume attack windows the baseline misses. gRPC microservices nearly match monolithic accuracy adding under 2ms per window, while the Kafka pipeline trails by roughly nine percentage points and adds about 27ms.
