**Issue Evaluation** Category: `bug` | Status: **Confirmed** The SSRF regression in `UrlHostGuard` has been verified. **Root Cause:** `UrlHostGuard.java:102` — `isAllowedHost(...)` uses `InetAddress.getByName(...)` which resolves only the first DNS answer. A hostname with mixed results (e.g. public + link-local/cloud-metadata) can bypass validation if the first answer is allowed while subsequent answers would be blocked. **Impact:** Security — the shared URL guard used by data-source save/query and LLM API bases can be bypassed via DNS rebinding or mixed-record responses. **Severity:** high An automated fix proposal can be generated.
