Debian Bug : #955018
It was discovered that there was two issues in shiro, a security
framework for Java application:
* CVE-2020-1957: Fix a path-traversal issue where a
specially-crafted request could cause an authentication bypass.
* CVE-2020-11989: Fix an encoding issue introduced in the handling
of the previous CVE-2020-1957 path-traversal issue which itself
could have also caused an authentication bypass.
For Debian 9 "Stretch", these issues have been fixed in shiro version

We recommend that you upgrade your shiro packages.
