Routinator exits when accepting an incoming HTTP or RTR connection fails

Published Jun 8, 2026

Description

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.

Affected products

Remediation

Vendor solution

This issue is fixed in 0.15.2 and all later versions.

Red Hat statement

Important: Routinator is susceptible to a denial of service when its HTTP or RTR server is exposed to untrusted networks. A remote attacker can exhaust available file descriptors by opening numerous connections, causing the service to exit and disrupting RPKI validation. This impact is significant for deployments relying on Routinator for critical routing infrastructure.

Red Hat mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
