The update manifest -- which contains the version number, download URL, and signature -- is fetched over TLS but is never itself signed or authenticated. Because the only anti-rollback check compares the manifest's version field against the current version, and that field is unsigned, an attacker who can serve a crafted manifest can force installation of any older signed release without possessing the developer's private key.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":32,"depthScoreParts":{"impact":32.5,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
