Summary
Affected versions of the `alloy-json-abi` crate did not properly handle parsing of malformatted JSON ABI strings. The `JsonAbi::parse` method can be tricked into a stack overflow when processing specially crafted input. This stack overflow can lead to a crash of the application using this crate, potentially causing a denial of service. The flaw was corrected in commit [4790c47](https://github.com/alloy-rs/core/commit/4790c47518024bd391bbd6815b00f501bad76a15).
