Aias00 opened a new issue, #6748:
URL: https://github.com/apache/shenyu/issues/6748
- severity: Medium
- files:
`shenyu-plugin/shenyu-plugin-mcp-server/src/main/java/org/apache/shenyu/plugin/mcp/server/McpServerPlugin.java:608-613`
- description: The SSE `/message` endpoint returns
`String.format("{\"message\":\"%s\"}", result.getResponseBody())` then
`responseBody.getBytes()`. Any `"`/`\`/control char in the message breaks the
JSON. `getBytes()` uses platform default charset (inconsistent with line 479
which uses `StandardCharsets.UTF_8`).
- impact: Malformed JSON for messages containing quotes/backslashes;
encoding corruption for non-ASCII.
- suggested_fix: Serialize with shared `ObjectMapper` and
`getBytes(StandardCharsets.UTF_8)`.
- confidence: High
- related_existing: none — PERF-22 is perf; this is escaping/encoding.
