Every PaperCut vulnerability the US government has confirmed attackers are using, newest first, with each bug’s EPSS (predicted attack chance) and VEDAS (exploit evidence) scores and any free Nuclei or Suricata detection rule. US federal agencies must fix KEV-listed bugs by a deadline; everyone else should treat the list as “patch first”.
