**Issue Evaluation** Category: `bug` | Status: **Confirmed** The reported issue is valid. The Prometheus metrics source applies bounds on response bytes, series count, and sample count, but does not limit per-series label cardinality or label value length. A malicious or misconfigured metrics endpoint could return series with thousands of labels or very long label values, bypassing the existing coarse-grained limits. **Root Cause:** Missing per-series label count and value length constraints in the Prometheus response parser. **Impact:** Potential memory exhaustion or excessive allocation from unbounded label data; defense-in-depth gap. **Severity:** medium Adding per-series label cardinality and value length bounds is a sound hardening measure. *Automated evaluation by RockteMQ-AI* -- This is an automated message from the Apache Git Service.
