However, this validation is performed only on the initial URL.\n\nSince Playwright automatically follows HTTP redirects (301/302) by default, an attacker can bypass the validation by providing a safe URL that redirects to a restricted internal network address (e.g., localhost, Docker container network, or Cloud Metadata).\n\nThis allows the application to access internal services despite ENABLE_RAG_LOCAL_WEB_FETCH being set to False\n\n### Details\nRoot Cause\n\nThe application validates the initial user-provided URL using self._safe_process_url_sync(url). This correctly resolves the domain and ensures it does not point to a private IP.\n\nThe application then calls page.goto(url). By default, Playwright automatically follows HTTP redirects (301/302).\n\nThe Bypass: If the destination server returns a redirect to an internal IP (e.g., 127.0.0.1 or 169.254.169.254), the browser follows it without re-validating the new destination. The initial validation is bypassed because it only checked the first URL, not the entire redirect chain.\n\n```python\nf","public_affected_ranges":["<= 0.9.5"]}],"null_published_at":"2026-11-04T10:04:27.918Z","source_updated_at":"2026-07-20T21:07:59.000Z","source_disclosed_at":"2026-06-17T17:55:44.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-04T02:47:44.783Z"}],"next_cursor":null,"snapshot_revision":"42594"}
