PaperCut Issues Second Emergency Patch as Attackers Exploit Print Management Software

Security Week · 31 Aug 2026

Key Takeaway If your business uses PaperCut, apply the latest patch immediately and check for signs of compromise, as attackers are already exploiting these vulnerabilities.

PaperCut, a widely used print management platform, has issued a second emergency patch to address vulnerabilities that are already being exploited by attackers. The flaws are now officially tracked as CVE-2026-82078 and CVE-2026-81578, and the fact that a follow-up patch was needed suggests the initial fix may not have fully closed the security gap.

PaperCut software is commonly deployed in schools, government offices, and small-to-medium businesses to manage printing across networks, making it an attractive target for attackers looking for a foothold into internal systems. Vulnerabilities in tools like this have historically been used as an entry point for broader network compromise, including ransomware deployment, so any organisation running PaperCut should treat this as a priority issue.

Businesses using PaperCut should update to the latest patched version immediately and verify the update was applied correctly, since the emergence of a second patch indicates the situation is still evolving. IT teams should also monitor PaperCut's official advisories for further updates and check server logs for any signs of unusual activity predating the patch.
