Since I have received I few direct (off-mailing-list/off-twitter)
queries on this,
I decided to blog about it:
https://cowtowncoder.medium.com/jackson-is-not-affected-by-log4j-logback-cves-fdebf152057f
So, TL;DNR; -- Jackson is NOT vulnerable to any of CVEs that affect
log4j and logback. This is because Jackson does not do any direct
logging of its own, using either framework.
So for once there is a simple answer to a big question. :)
Happy Holidays,
