Course-tencent-cloud through 2.0.1 contains an improper restriction of authentication attempts vulnerability that allows unauthenticated attackers to brute force 6-digit SMS/email verification codes, which are never invalidated or attempt-limited. Attackers who know a victim's phone or email can trigger a code and rotate source IPs against the password reset and verify login endpoints to take over accounts.
