Description
A deserialization flaw was discovered in jackson-databind through 2.9.10.4. It could allow an unauthenticated user to perform code execution via ignite-jta or quartz-core: org.apache.ignite.cache.jta.jndi.CacheJndiTmLookup, org.apache.ignite.cache.jta.jndi.CacheJndiTmFactory, and org.quartz.utils.JNDIConnectionProvider.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.fasterxml.jackson.core:jackson-databind, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update com.fasterxml.jackson.core:jackson-databind to 2.9.10.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-10650 is resolved across your whole dependency graph.
Workarounds
Do not deserialise data from untrusted sources: where the format allows it, restrict deserialisation to an explicit allowlist of expected types, and prefer a data-only format (JSON, Protobuf) over one that can reconstruct arbitrary objects until you can upgrade.
