Doc Text:
A flaw was found in Routinator. A remote attacker can exploit this vulnerability by opening a large number of connections to the HTTP or RTR (Resource Public Key Infrastructure (RPKI) to Router) server. This can cause Routinator to exit, leading to a Denial of Service (DoS) for affected services. This issue primarily impacts users who expose their HTTP or RTR server to untrusted networks.

Description OSIDB Bzimport 2026-06-08 15:02:10 UTC 
Routinator exits on any error when accepting incoming HTTP or RTR connections, including ones it can recover from such as running out of file descriptors. This condition can be triggered maliciously by an attacker by opening a large number of connections to the HTTP or RTR server.

This only affects users that make their HTTP or RTR server available to untrusted networks.
