Vulnerability in Typemill (CVE-2026-71213)
Summary
Vulnerability in Typemill (CVE-2026-71213). Confidential information can be exposed externally. Exploitable via POST /tm/login.
Original description
The description as published by the source.
Typemill's login endpoint (POST /tm/login, ControllerWebAuth::login()) performs no rate-limiting, failed-attempt counting, or account lockout when captcha is disabled, which is the default configuration. An unauthenticated attacker can send unlimited password-guessing requests against any account, including administrators, with no throttling. The only attempt-counting/lockout logic present in the same file protects an optional secondary email-authcode step and does not apply to the primary password check.

Concrete steps and command examples for SOC/SRE teams to execute in order
-
1Identify exposure identify
grep -r 'Typemill' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で
Typemillを grep し、稼働しているサービス・バージョンを把握する。 -
2Hunt for indicators of compromise detect
grep 'POST /tm/login' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで
POST /tm/loginへの異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。 -
3Post-deployment verification verify
Replay attack against POST /tm/login on staging to confirm patch closes the vectorパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 2 と同じログクエリでアラート再発が無いか継続監視。
