CVE-2020-11619

A flaw was found in jackson-databind 2.x. The interaction between serialization gadgets and typing is mishandled. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

8.1 (High)
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
CWE-502 - Deserialization of Untrusted Data
Vendor Fix For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 https://access.redhat.com/errata/RHSA-2020:2320
Workaround The following conditions are needed for an exploit, we recommend avoiding all if possible: * Deserialization from sources you do not control * `enableDefaultTyping()` * `@JsonTypeInfo using `id.CLASS` or `id.MINIMAL_CLASS`
