About the CISA KEV catalog
CISA lists the CVEs with reliable evidence of exploitation in the wild. Each entry carries a required action and a due date that binds US federal agencies; for everyone else it is the clearest signal that a fix cannot wait.

The Known Exploited Vulnerabilities catalog is maintained by the US Cybersecurity and Infrastructure Security Agency and updated as exploitation is confirmed. Being listed raises the priority of a fix; not being listed is never read as safe. Patcharo reads the feed at every synchronisation, keeps the due date and the ransomware flag exactly as CISA publishes them, and shows them next to the vendor's fixed releases so that the two questions, is it exploited and which release fixes it, are answered together.
