Similar to #463, the latest msgpack-java (version 0.8.16) still uses jackson-databind (version 2.8.11.1) that has security vulnerabilities.
See https://www.sourceclear.com/vulnerability-database/security/deserialisation-of-untrusted-data/java/sid-8093.
- The earliest recommended version to upgrade to is 2.9.9, as the whole 2.8.x range is affected by this or other issues.
P.S. Unfortunately this specific vulnerability is due to an incomplete fix of the same CVE that caused #463, so @komamitsu is spot on when saying
It's like whack-a-mole...
