orbisai0security opened a new pull request, #40454:
URL: https://github.com/apache/superset/pull/40454
## Summary
Fix high severity security issue in `superset/db_engine_specs/impala.py`.
## Vulnerability
| Field | Value |
|-------|-------|
| **ID** | V-001 |
| **Severity** | HIGH |
| **Scanner** | multi_agent_ai |
| **Rule** | `V-001` |
| **File** | `superset/db_engine_specs/impala.py:213` |
| **Assessment** | Confirmed exploitable |
**Description**: The Impala database engine spec makes an HTTP POST request
using a URL that may be influenced by database connection parameters configured
by users with database creation privileges. If the URL is derived from
user-controllable connection settings, an attacker could redirect requests to
internal services.
## Changes
- `superset/db_engine_specs/impala.py`
## Verification
- [x] Build passes
- [x] Scanner re-scan confirms fix
- [x] LLM code review passed
## Security Invariant
> **Property**: The security boundary is maintained under adversarial input
<details>
<summary>Regression test</summary>

/**
* Security Property:
* The Impala engine spec must never make HTTP POST requests to URLs derived
from
* user-controllable connection parameters that point to internal/private
network
* addresses, SSRF targets, or otherwise unauthorized destinations.
*
* WHAT MUST ALWAYS BE TRUE:
* - URLs constructed from user-supplied connection parameters must be
validated
* against an allowlist of permitted hosts/schemes before any HTTP request
is made.
* - Internal network addresses (loopback, RFC1918, metadata services) must
be rejected.
* - Non-HTTP(S) schemes must be rejected.
* - Redirects to internal services must not be followed blindly.
