@Lukasa @FranzBusch @tbkka - I'm putting this up in draft for thoughts. The Protobuf JSON spec doesn't formally say what counts for depth, but we already had "Struct" and "List" counting, "Value" is the potential gap here. Since this would have impact on things that current parse, but could be dangerous, I'm not sure if we should change things, or just let it go. Thoughts? |
Use `defer` to avoid accidentally missing a call on a `return` path. This also counts "Value" as an object; that effectively halves the depth of some raw JSON parsed into a "Struct", but it was allowing what might be a stack bomb attempt to be parsed in some cases.
