**Issue Evaluation** Category: `type/bug` | Status: **Confirmed** The reported issue has been verified against the current codebase (`develop` branch). **Root Cause:** `MQVersion.getVersionDesc(int)` and `MQVersion.value2Version(int)` check `if (value >= length)` but do not guard against negative values. A negative `value` causes `ArrayIndexOutOfBoundsException` when accessing `versions[value]`. **Impact:** Any code path passing a negative version number (e.g., from corrupted data or protocol error) crashes instead of returning a safe default. **Severity:** low **Affected code:** `common/src/main/java/org/apache/rocketmq/common/MQVersion.java` An automated fix proposal will be generated.
