the CONFSERVER-104517 advisory.

  - Improper Authentication vulnerability in Apache Tomcat meant that in some circumstances (e.g. CLIENT-CERT,
    SPNEGO) that a user would be authenticated even if the user did not exist in the DataSourceRealm. This
    issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.24, from 10.1.0-M1 through 10.1.57, from 9.0.0.M1
    through 9.0.120. The following versions were EOL at the time the CVE was created but are known to be
    affected: from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Other unsupported versions may also be
    affected. Users are recommended to upgrade to version 11.0.25, 10.1.58 or 9.0.121, which fix the issue.
