| Title | ag-ui-protocol ag-ui v1.0 CWE-755 |
|---|
| Description | Event JSON is parsed with kotlinx.serialization without a depth limit. Deeply nested JSON throws StackOverflowError — an Error, not an Exception — which escapes the parser's catch(Exception) handler and terminates the JVM/Android process.
Process termination (Kotlin stack-overflow path) or gradual unbounded memory growth (the accumulation items), triggered by a malicious or misbehaving agent endpoint. Availability only. |
