A flaw has been found in FoundationAgents MetaGPT up to 0.8.1. This vulnerability affects the function ActionNode.xml_fill of the file metagpt/actions/action_node.py of the component XML Handler. Executing a manipulation can lead to improper neutralization of directives in dynamically evaluated code. The attack may be launched remotely. The exploit has been published and may be used. The project was informed of the problem early through a pull request but has not reacted yet.

jackson-databind: @JsonView ypassed for @JsonUnwrapped container properties on deserialization

CVE-2026-59889 [MEDIUM] CWE-863 jackson-databind: @JsonView ypassed for @JsonUnwrapped container properties on deserialization
jackson-databind: @JsonView ypassed for @JsonUnwrapped container properties on deserialization
## Summary
`UnwrappedPropertyHandler.processUnwrapped()` replays the buffered JSON for a `@JsonUnwrapped` property by iterating its properties and calling `prop.deserializeAndSet()` with **no `prop.visibleInView(ctxt.getActiveView())` guard** — the exact guard `processUnwrappedCreatorProperties()` received in the #5971 / GHSA-rcqc-6cw3-h962 fix, and the guard `BeanDeserializer.deserializeWithUnwrapped` applies to directly-matched properties. As a result, a property annotated with both `@JsonView(PrivilegedView.class)` and `@JsonUnwrapped` is written from attacker JSON even when deserializing under a more-restrictive active view.
**Correction to the original framing (runtime-verified):** the gap
