What is CVE-2026-72756?

Routinator has a vulnerability that causes the software to exit unexpectedly when it encounters an rsync URI for a file retrieved over RRDP with path specifications that are incompatible with file system constraints, such as excessively long filenames or directory names that conflict with pre-existing filenames. This can lead to potential disruptions in service and requires careful consideration of file management in configuration to prevent operational issues.
