Description
Spring HATEOAS's internal PropertyUtils.createObjectFromProperties method, used by the Collection+JSON and UBER media type deserializers, performs bean property binding via reflection without consulting Jackson access-control annotations.
Affected versions: Spring HATEOAS 1.5.0 through 1.5.6; 2.3.0 through 2.3.4; 2.4.0 through 2.4.1; 2.5.0 through 2.5.2; 3.0.0 through 3.0.3.

spring hateoasvmwareDetection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.springframework.hateoas:spring-hateoas, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.springframework.hateoas:spring-hateoas to 3.0.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-41006 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.
