MEDIUM 5.9EPSS 0.27%

Does this matter?

Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.

Description

Default configurations of Apache Shiro send sensitive cookies in HTTPS session without 'Secure' attribute. This issue affects Apache Shiro from 1.0 to 2.1.0, and 3.0.0-alpha-1. Users are recommended to upgrade to version 2.1.1, or 3.0.0-alpha-2 or later, which fixes the issue. In the affected versions, Shiro-native session manager, as well as Remember-Me manager sends JSESSIONID and rememberMe cookies without 'secure' attribute by default.
