Vulnerability
The password-reset endpoint https://admin.alwaysdata.com/password/lost/ accepts unlimited requests for any e-mail address without rate limiting, CAPTCHA, or cooldown.

Impact
- An attacker can flood any user’s mailbox with hundreds/thousands of password-reset e-mails
- Targeted denial-of-service against a specific user
- PTP (Password-reset Token Poisoning) & Password Reset Abuse
- Loss of trust and bypassing of normal security controls

Steps to Reproduce
1. Go to https://admin.alwaysdata.com/password/lost/ 2. Enter any valid e-mail address that has an alwaysdata account
3. Capture the request in Burp Suite / Intruder
4. Send it to Intruder, remove all payloads except the e-mail parameter
5. Start the attack with multiple threads
→ The victim instantly receives a flood of password-reset e-mails (see attached PoC video/screenshots)

Proof of Concept
(Attach your video or screenshots here – click “Choose File”)

Recommended Fix
Implement at least one of the following on the password-reset endpoint:
- Strict per-IP + per-e-mail rate limiting (e.g., max 3–5 requests per hour)
- CAPTCHA (hCaptcha/reCAPTCHA)
- Temporary account lockout after X attempts
