**Issue Evaluation** Category: `type/bug` | Status: **Confirmed** The issue is valid. `GET_LITE_GROUP_INFO` does not validate the `topK` parameter, allowing negative or excessively large values. A negative `topK` could cause unexpected behavior in downstream sorting/limiting logic, while an unbounded `topK` could lead to excessive memory allocation or slow responses when a group has many subscriptions. The fix should clamp `topK` to a reasonable range (e.g., 1 to a configured maximum, defaulting to something like 100). This is consistent with how other query endpoints validate similar parameters. An automated fix proposal may be generated. Reply `/approve` to proceed with PR generation. --- *Automated evaluation by github-manager* -- This is an automated message from the Apache Git Service.
