CVE-2019-12384  (opens in a new tab)
CWE-502  (opens in a new tab)

How to fix?

Upgrade Ubuntu:26.04 jackson-databind to version 2.9.8-3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jackson-databind package and not the jackson-databind package as distributed by Ubuntu. See How to fix? for Ubuntu:26.04 relevant fixed versions and status.

FasterXML jackson-databind 2.x before 2.9.9.1 might allow attackers to have a variety of impacts by leveraging failure to block the logback-core class from polymorphic deserialization. Depending on the classpath content, remote code execution may be possible.
