CVE-2026-72756 Details
Description
Routinator exits when an rsync URI for a file obtained over RRDP contains a path that cannot be stored on disk, such as too long file names, and folder names that overlap with existing file names.
A denial-of-service vulnerability has been identified in NLnet Labs Routinator versions prior to and including 0.15.2. The issue occurs when an rsync URI, used to retrieve files over RRDP, includes a path that cannot be properly stored on disk. This can happen with excessively long file names or folder names that conflict with existing file names. When Routinator encounters such a malformed URI, it exits unexpectedly, leading to a disruption in service.
Users can address this vulnerability by upgrading to Routinator version 0.15.3 or later.
