CVE-2026-49232 Details
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.
A denial-of-service vulnerability has been identified in NLnet Labs Routinator versions prior to and including 0.15.1. The issue arises because Routinator exits upon encountering any error while handling incoming HTTP or RTR connections. This includes recoverable errors, such as depleting available file descriptors. An attacker can exploit this vulnerability by opening a large number of connections to the HTTP or RTR server, causing Routinator to crash. This issue only affects users who expose their HTTP or RTR server to untrusted networks.
Users are advised to upgrade to Routinator version 0.15.2 or later.
