Unauthorized account confirmation via GET link prefetch
Published Apr 15, 2025 · Updated Apr 16, 2025
Authentication bypass in Alembic Ash Authentication before 4.7.0 allows remote attackers to confirm new accounts through prefetched email links. The account-confirmation endpoint performs the state-changing confirmation on a GET request, so email clients and security tools can activate a registration link without explicit recipient action. The attacker needs only to register a new account with another person's email; the flaw neither grants access to existing accounts nor exposes private data.
