User-supplied parameters are echoed into HTML without escaping via print_test_result(). No authentication is required.\n\nA Content Security Policy (script-src 'self') prevents inline JavaScript execution, but the CSP is missing a form-action directive, allowing exploitation via credential-phishing form injection and  open redirects.\n\n### Impact\n- Credential phishing: Attacker crafts a URL that renders a fake login form on the real MantisBT admin page. Admin credentials are submitted to an attacker-controlled server.\n- Open redirect: Victim is silently redirected to a phishing or malware site.\n- UI manipulation: CSS injection can hide legitimate page content and overlay attacker-controlled HTML, enabling social engineering.\n\n### Patches\n- https://github.com/mantisbt/mantisbt/commit/0f32ceabadc745239754962df91a51d5d51e3fd7\n- https://github.com/mantisbt/mantisbt/commit/f2191a0d8ce438bf74171d496cf721dae025a5c0\n\n### Workarounds\nRemove the `/admin` directory, as recommended in the Admin Guide\n\n##","public_affected_ranges":["ECOSYSTEM: introduced 0; fixed 2.28.4"]}],"null_published_at":"2026-10-31T22:13:01.442Z","source_updated_at":"2026-07-15T18:41:49.232Z","source_disclosed_at":"2026-07-15T18:25:36.000Z","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":"2026-10-31T21:41:59.946Z"}],"next_cursor":null,"snapshot_revision":"42594"}
