GoKawiilPaperCut's August patch failures show zero-day response now measured in hours
PaperCut disclosed active exploitation of PaperCut NG/MF servers on August 27 with no CVE, no available exploit sample, and no patch. An emergency fix issued the next day was bypassed within hours, and a third patch only arrived on September 1, leaving customers exposed for roughly six days while attackers were already using the flaw in live attacks. A security researcher uses the episode to argue that the industry's old assumptions about response timelines no longer hold.
