CVE-2026-118505: team-alembic ash_authentication brute force protection bypass

CVE-2026-118505 · Severity: info · Published 2026-11-03

ash_authentication is an Elixir authentication library that protects sign-in and password reset operations by limiting failed attempts. A configuration bug allows attackers to bypass these protections on custom actions, sign-in with OTP, and registration-enabled signup flows, enabling unlimited password guessing and one-time password enumeration attacks.

Technologies: Team-Alembic Ash Authentication. Vendors: Team-Alembic.

Technical details

The brute_force_strategy preparation is only applied to generated actions, not to custom resource-defined actions. When developers override password, magic link, or OTP sign-in actions, the preparation is skipped; additionally, OTP sign-in with registration enabled is a create action, which do not execute preparations. An unauthenticated attacker can make unlimited authentication attempts without rate limiting.
