CVE-2026-59245 Apache Airflow FAB provider: FAB auth manager: a DAG named "DAGs" hijacks the global all-DAGs permission (access_control privilege escalation via resource_name() collision)

In the Apache Airflow FAB auth manager, a DAG whose dagid is DAGs collided with the global all-DAGs permission resource name produced by resourcename, so a user granted per-DAG accesscontrol on that one DAG was silently granted the global all-DAGs permission privilege escalation. The escalation...

GNSS Spoofing Detection in TDD Networks: A 3GPP Standards-Based Security Framework

Time Division Duplex TDD mobile networks require synchronization accuracy of $\pm$1.5 $μ$s 3GPP TS 38.104, with GNSS-disciplined grandmaster clocks as the predominant timing source. GNSS spoofing -- now a documented operational threat -- can corrupt timing across all downstream base stations, yet...
