Pterodactyl TOTPs can be reused during validity window
Date: 2026-01
Affected: composer/pterodactyl/panel
Attack vector: auth-bypass
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2025-69197
CWE: CWE-287
CVSS: 6.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

### Summary When a user signs into an account with 2FA enabled they are prompted to enter a token. When that token is used, it is not sufficiently marked as used in the system allowing an attacker that intercepts that token to then use it in addition to a known username/password during the token validity window. This vulnerability requires that an attacker already be in possession of a valid username and password combination, and intercept a valid 2FA token (for example, during a screen share). The token must then be provided in addition to the username and password during the limited token validity window. The validity window is ~60 seconds as the Panel allows at most one additional window to the current one, each window being 30 seconds.
