Both scanners walk the input with `StringCharacterIterator.next()` but only compare against a delimiter, so once the iterator reaches `CharacterIterator.DONE` (`￿`) they loop forever. The string scanner (`string()`, line 210, `while (c != sep)`) also appends `￿` to a `StringBuilder` every iteration, so it fills the heap and throws `OutOfMemoryError`, taking down the JVM. The comment scanner (`skipWhiteSpace()`, lines 89-92, `while (c != '\\n')`) pins a thread at 100% CPU with no allocation.\n\nThis is reachable with a single message. `JsonRpcServer` and `JsonRpcClient` fall back to `DefaultJsonRpcMapper` whenever no mapper is passed (`JsonRpcServer.java:84` and `:114`, `JsonRpcClient.java:186`), and that mapper hands the raw message body straight to `JSONReader.read()` (`DefaultJsonRpcMapper.java:42` for the server request, `:52` for the client reply). A caller that can publish to the RPC request queue hangs the server; a malicious or MITM'd JSON-RPC service does the same to a client.\n\n## Proof of concept\n\nAgainst `amqp-client` 5.36.0 from Maven Central:\n\n```java\nimport com.rabbitmq.tools.jsonrpc.DefaultJsonRpcMapper;\n\npublic class Poc {\n    public static void main(String[] args) {\n        DefaultJsonRpcMapper mapper = new DefaultJsonRpcMapper();\n        mapper.parse(\"{\\\"method\\\":\\\"x\", String.class); // unterminated string\n        // mapper.parse(\"//\", String.class);           // unterminated // comment\n        System.out.println(\"unreachable\");\n    }\n}\n```\n\n`java -Xmx64m -cp amqp-client-5.36.0.jar:. Poc` throws `OutOfMemoryError: Java heap space` in about 0.1s and never prints. Swapping in the `//` line spins at 100% CPU and never returns. A well-formed body such as `{\"method\":\"x\"}` returns immediately.\n\n## Impact\n\nAvailability. One small, unauthenticated message stops a JSON-RPC endpoint: the unterminated string exhausts the heap, the unterminated comment pins a thread forever. Neither is recoverable per request - `JsonRpcServer.doCall` only catches `ClassCastException`, and an `OutOfMemoryError` affects the whole process.\n\n## Scope and fix\n\nOnly applications using the JSON-RPC-over-AMQP tooling (`com.rabbitmq.tools.jsonrpc`) with the default `DefaultJsonRpcMapper` are affected. `DefaultJsonRpcMapper` and `JSONReader` are deprecated in favour of `JacksonJsonRpcMapper`, but both still ship and remain the default when no mapper is supplied.

Both scanners walk the input with `StringCharacterIterator.next()` but only compare against a delimiter, so once the iterator reaches `CharacterIterator.DONE` (`￿`) they loop forever. The string scanner (`string()`, line 210, `while (c != sep)`) also appends `￿` to a `StringBuilder` every iteration, so it fills the heap and throws `OutOfMemoryError`, taking down the JVM. The comment scanner (`skipWhiteSpace()`, lines 89-92, `while (c != '\\n')`) pins a thread at 100% CPU with no allocation.\n\nThis is reachable with a single message. `JsonRpcServer` and `JsonRpcClient` fall back to `DefaultJsonRpcMapper` whenever no mapper is passed (`JsonRpcServer.java:84` and `:114`, `JsonRpcClient.java:186`), and that mapper hands the raw message body straight to `JSONReader.read()` (`DefaultJsonRpcMapper.java:42` for the server request, `:52` for the client reply). A caller that can publish to the RPC request queue hangs the server; a malicious or MITM'd JSON-RPC service does the same to a client.\n\n## Proof of concept\n\nAgainst `amqp-client` 5.36.0 from Maven Central:\n\n```java\nimport com.rabbitmq.tools.jsonrpc.DefaultJsonRpcMapper;\n\npublic class Poc {\n    public static void main(String[] args) {\n        DefaultJsonRpcMapper mapper = new DefaultJsonRpcMapper();\n        mapper.parse(\"{\\\"method\\\":\\\"x\", String.class); // unterminated string\n        // mapper.parse(\"//\", String.class);           // unterminated // comment\n        System.out.println(\"unreachable\");\n    }\n}\n```\n\n`java -Xmx64m -cp amqp-client-5.36.0.jar:. Poc` throws `OutOfMemoryError: Java heap space` in about 0.1s and never prints. Swapping in the `//` line spins at 100% CPU and never returns. A well-formed body such as `{\"method\":\"x\"}` returns immediately.\n\n## Impact\n\nAvailability. One small, unauthenticated message stops a JSON-RPC endpoint: the unterminated string exhausts the heap, the unterminated comment pins a thread forever. Neither is recoverable per request - `JsonRpcServer.doCall` only catches `ClassCastException`, and an `OutOfMemoryError` affects the whole process.\n\n## Scope and fix\n\nOnly applications using the JSON-RPC-over-AMQP tooling (`com.rabbitmq.tools.jsonrpc`) with the default `DefaultJsonRpcMapper` are affected. `DefaultJsonRpcMapper` and `JSONReader` are deprecated in favour of `JacksonJsonRpcMapper`, but both still ship and remain the default when no mapper is supplied.
