CVE-2022-45143: Apache Tomcat

High severity, CVSS 7.5. EPSS: 2.5% chance of exploitation in the next 30 days.

The JsonErrorReportValve in Apache Tomcat 8.5.83, 9.0.40 to 9.0.68 and 10.1.0-M1 to 10.1.1 did not escape the type, message or description values. In some circumstances these are constructed from user provided data and it was therefore possible for users to supply values that invalidated or manipulated the JSON output.

Affected products

• Apache Tomcat: from 9.0.40, before 9.0.69 (fixed in 9.0.69); version 8.5.83 only; version 10.1.0 only; version 10.1.1 only
