PaperCut Rushes Out Emergency Fix for Actively Exploited Security Flaw

Security Week · 28 Aug 2026

Key Takeaway If your business uses PaperCut NG or MF, apply the emergency patch immediately or implement the recommended mitigations to avoid falling victim to active exploitation.

Print management software provider PaperCut has released an emergency patch after discovering that a security flaw in its NG and MF products is being actively exploited by attackers. A formal vulnerability identifier (CVE) has not yet been assigned, but the company is urging all NG/MF users to install the patch immediately.

Alongside the patch, PaperCut has published mitigation guidance for organisations that may not be able to update straight away, helping to reduce risk while the fix is rolled out. Because the vulnerability is already being used in real-world attacks, delaying action increases the chance of compromise.

Small and medium businesses using PaperCut NG or MF for print management should treat this as a priority update. Attackers often target widely used business software precisely because many organisations are slow to patch, making prompt action an effective defence.
