The engine passes the value to `voltFile.ReadLinesOrLiteral`, which reads lines from any file path accessible to the dalfox process and embeds each line as an XSS payload in outbound HTTP requests directed at the attacker-controlled target URL. Because the server has no API key by default, an unauthenticated network attacker can exfiltrate the contents of arbitrary files on the dalfox host by reading them line-by-line through scan traffic.\n\n## Severity\n\n**High** (CVSS 3.1: 7.5)\n\n`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N`\n\n- **Attack Vector:** Network — server binds to `0.0.0.0:6664` by default; reachable by any network peer.\n- **Attack Complexity:** Low — no preconditions beyond network access; `skip-discovery` and `param` are both attacker-supplied, so the code path is fully under attacker control.\n- **Privileges Required:** None — `--api-key` defaults to `\"\"`, so the auth middleware is not registered.\n- **User Interaction:","public_affected_ranges":["<= 2.12.0"]}],"null_published_at":"2026-11-07T07:07:39.834Z","source_updated_at":"2026-06-08T23:50:10.000Z","source_disclosed_at":"2026-05-12T15:08:13.000Z","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":"2026-11-07T00:50:36.189Z"}],"next_cursor":null,"snapshot_revision":"42594"}
