Description
Flame through 2.4.0 contains an improper restriction of excessive authentication attempts vulnerability in the POST /api/auth login endpoint that allows unauthenticated attackers to brute-force the admin password. Attackers can submit unlimited password guesses without rate limiting, attempt counters, lockouts, or delays to gain full administrator access and modify application configuration.
