CVE-2026-49233 Details
Description
Routinator does not properly check the module component of rsync URIs, which are used to create the file system paths for the Routinator cache. This allows for path traversal by having a module name containing .., potentially providing an attacker access to the entire Routinator rsync cache.
A path traversal vulnerability has been identified in Routinator versions prior to and including 0.15.1. The issue arises because Routinator fails to properly validate the module component of rsync URIs. These URIs are used to generate file system paths for the Routinator cache. As a result, an attacker could craft a module name containing '..' to traverse directories, potentially gaining access to the entire Routinator rsync cache.
Users are advised to upgrade to Routinator version 0.15.2 or later.
