nvd epss: 0.13872 epssPercentile: 0.9648 ingestedAt: '2026-10-14T17:44:53.592Z' --- ## Overview The Expression Language (EL) implementation in Apache Tomcat 6.x before 6.0.44, 7.x before 7.0.58, and 8.x before 8.0.16 does not properly consider the possibility of an accessible interface implemented by an inaccessible class, which allows attackers to bypass a SecurityManager protection mechanism via a web application that leverages use of incorrect privileges during EL evaluation. ## Affected -
