0 CVE-2026-91039 is an authentication bypass vulnerability in team-alembic's ash_authentication library affecting versions from 5.0.0-rc.10 up to but not including 5.0.0-rc.14. The flaw allows an attacker controlling one identity-provider connection in a dynamic_oidc strategy to authenticate as a local user established through a different connection due to improper namespacing of identity strategies. This occurs because the connection_id used to namespace identities is not persisted correctly, causing multiple identity connections to share the same subject space. The vulnerability has a critical severity with a CVSS 4.0 score of 9.1. No official patch or vendor advisory is provided in the input data.
