No non-default configuration is required; the import is reached through the administrator bookmark-import action. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which uses a hardened parser that disables external entities and document type declarations.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":42.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
