Status

Pending upstream fix

Impact

jackson-core 2.15.2 is bundled in zookeeper-3.9 and is vulnerable to GHSA-72hv-8253-57qq. The fix requires updating to jackson-core 2.18.6, however bumping the jackson.version property via pombump causes compilation failures in zookeeper-server (package com.fasterxml.jackson.core does not exist). This appears to be a classpath resolution issue with how jackson-core is resolved as a transitive dependency. Upstream ZooKeeper 3.9 has not addressed this (still on 2.15.2).
