Barracuda’s Application Security Insight data reveals that the average web application contains 20 security vulnerabilities that could be exploited by attackers to steal data, compromise accounts or gain unauthorized access to systems.
These security vulnerabilities can be grouped into types. This article highlights the seven key types of vulnerability detected over five months in 2026, how attackers can exploit them, and the action security admins can take to strengthen protection and mitigate risk. These seven categories represent approximately 90% of all vulnerabilities detected.
The findings show that everyday configuration mistakes, brand impersonation and information disclosure issues remain widespread.
An average of 20 security flaws per web application means attackers have multiple opportunities to probe, test and exploit weaknesses. While not every flaw is critical on its own, several low- and medium-risk vulnerabilities can be combined to reveal sensitive information, steal credentials or gain unauthorized access to systems.
