What happened

Authorization Bypass Through User-Controlled Key vulnerability in team-alembic ash_authentication allows a user with an account to install a TOTP secret they control on another user's account, and then sign in as that user or hold their second factor.

AshAuthentication.Strategy.Totp.ConfirmSetupChange verified a setup token but did not check that it was issued to the record being confirmed, so an attacker's own pending secret could be confirmed onto another user's record.

The TOTP setup changes, ConfirmSetupChange, GeneratePendingSetupChange and GenerateSecretChange, also marked their changesets as AshAuthentication interactions, which the standard AshAuthenticationInteraction policy bypass lets through.

A policy limiting setup and confirm_setup to the actor's own record therefore never ran when an application exposed those actions by record key, and a direct setup call on another user's record returned that user's pending secret and setup token.

About this data

This record was ingested from a data source. Retrieved: Nov 3, 2026, 19:05 UTC. Ingestion is not an independent editorial investigation.

NVD status: Deferred. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
