 **Vulnerability:** The CLI executor proxy lacked scheme validation for the user-controlled `remoteHost`, creating an SSRF vulnerability. The OAuth callback forwarder lacked prefix validation for `targetBase`, creating an open redirect vulnerability.
 **Learning:** Taint analysis revealed that input passed from management configurations or remote host specifications must be strictly validated before being used in HTTP requests or redirect targets to prevent protocol abuse and unauthorized redirects.
 **Prevention:** Always enforce strict protocol validation (e.g., scheme is 'http' or 'https') for outbound requests and validate redirect targets against allowed prefixes (e.g., 'http://localhost' or '/').
+## 2026-11-11 - Fix SSRF via taint analysis in CLI Executor
+**Vulnerability:** A Server-Side Request Forgery (SSRF) vulnerability existed in `/app/internal/runtime/executor/cli_executor.go`. When constructing the `/run` endpoint URL for a remote host, the code copied a parsed URL by value (`targetURL := *parsedURL`) and manually cleared fields like `RawPath` and `Fragment`. If an attacker injected a URL with an `Opaque` field (e.g., `http://example.com;opaque=//malicious.com`), the `.String()` method would prioritize `Opaque` over the `Path`, potentially bypassing path constraints and redirecting the request to an unintended server.
+**Learning:** Copying parsed `url.URL` structures by value is risky because the `url.URL.String()` function relies on multiple internal fields (like `Opaque`) that can override the standard components (like `Path`).
+**Prevention:** Always construct a new `url.URL{}` struct literal explicitly and only copy the known, safe fields (e.g., `Scheme`, `Host`, `Path`, `RawQuery`, `User`) from the untrusted input to ensure predictable URL serialization.
