FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to conduct server-side request forgery (SSRF) attacks by leveraging failure to block the axis2-jaxws class from polymorphic deserialization.
MergeBase Comment
If you're running Jackson-Databind and Axis2 is also on your classpath, you better upgrade this one! If Axis2 is not on your classpath (a relatively rare situation these days - who uses SOAP anymore, anyway!?!), then you are safe, but it's always a good idea to stay on the latest version of jackson-databind if you can.
git clone
git log -p --first-parent jackson-databind-2.9.6..jackson-databind-2.9.7 -- src/main

Jackson-databind probably has more CVEs than any other open source Java library on the planet. But that is a bit misleading, because the CVE's tend to be associated with blacklist "gadget" entries added to jackson-databind's list of Java objects it will refuse to deserialize against. A good blog post at explains this in more detail.
