A security researcher discovered a rate-limiting vulnerability in Microsoft's password reset flow that could be exploited via concurrent requests to brute-force 7-digit security codes, bypassing encryption and rate limits to enable account takeover even on accounts with 2FA enabled. Microsoft patched the vulnerability and awarded a $50,000 bounty.
