Nitro has historically had very few security updates or patches (only 2 in the past 5 years). When security issues are identified, Nitro prioritizes them for resolution and release based on their risk and severity. If a security update is released in the future, it will be made available on this page for Nitro Personal (individual) users. Nitro Business customers with 11 or more users may contact their Nitro Account Manager for access to the security fix and deployment instructions. In the unlikely event of a high severity security fix, Nitro Enterprise customers with a dedicated Customer Success Manager will receive notice and fix deployment instructions. Security is a key concern and major design tenet for Nitro Engineering. Through proactive security design and testing, Nitro is proud to have had so few security updates.

Summary: Nitro has released an update for Nitro Pro 10 and Nitro Pro 11, which addresses two potential security vulnerabilities. If exploited, an attacker could access a user’s desktop computer, install a malicious program, and then get the user to open a malicious PDF file using a version of Nitro Pro that contains the vulnerability.
