| Titre | makeplane plane <=1.4.2 Use of Less Trusted Source |
|---|
| Description | Plane exposes multiple unauthenticated API endpoints that return distinguishable responses depending on whether a supplied email address belongs to a registered user. An AuthenticationThrottle (DRF AnonRateThrottle) rate-limits these endpoints, but the throttle key is derived from the X-Forwarded-For header without requiring a trusted proxy configuration (NUM_PROXIES is unset). An unauthenticated attacker can rotate the X-Forwarded-For value to bypass the rate limit and enumerate registered email addresses at arbitrary speed. |
