Timeline

2026-08-25	first spoke of it: 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.	NVD

What it is to other things

affects	apache/tomcat NVD
made_by	apache NVD

In words only, so not counted until a person confirms one:

made_by	`apache_software_foundation` NVD says “Apache Software Foundation”
affects	`apache_software_foundation/apache_tomcat` NVD says “Apache Software Foundation · Apache Tomcat”

Every value, with what each source said and its receipt
