The CVE-2025-XXXXX vulnerability in `serde-json-wasm` arises due to insufficient stack depth checks during recursive JSON parsing. When processing deeply nested JSON structures, the crate fails to limit recursion, leading to uncontrolled stack consumption. This can trigger a stack overflow, potentially crashing the application or enabling denial-of-service attacks. The issue affects versions prior to 1.0.1, where the parser recursively traverses nested objects without proper bounds.
