CVE-2026-72752 — MEDIUM (6.5)

Vulnerability Description

Routinator runs out of memory when the JSON output is requested many times concurrently. This condition can be triggered maliciously by an attacker by opening a large number of connections to the HTTP server. Additionally Routinator runs into a stack overflow and exits when a payload item with too much metadata is discarded at once. This only affects users that make their HTTP or RTR server available to untrusted networks.
