Improper authentication in PgBouncer 1.17.0 through 1.26.0 allows a remote attacker who knows the password of a user listed in auth_file to log in as any other user that authenticates using SCRAM, including PgBouncer admin users and backend superusers. A second StartupMessage sent during SCRAM authentication against a non-existent database is not rejected and switches the user being logged in as, while the SCRAM exchange is still verified against the keys of the first user.

CVE-2026-173706.4 MÉD—
———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain an access token for another user due to improper authentication. The sign-in flow does not sufficiently verify the identity of the user completing it, which could allow another user's identity to be assumed.4hCVE-2026-173588.2 ALT—
———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to bypass authentication across tenants due to improper authentication. Authentication checks are not sufficiently isolated between tenants, which could allow a user from one tenant to be accepted by another.4hCVE-2026-173268.1 ALT—
———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to bypass security restrictions due to improper authentication.4hCVE-2026-172406.5 MÉD—
———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote attacker to bypass security restrictions due to improper authentication. Authentication checks are not applied consistently, which could allow protected resources to be reached without valid credentials.4hCVE-2026-171589.9 CRÍ—
———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to gain elevated privileges due to improper authentication.4hCVE-2026-167209.8 CRÍ—
———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote attacker to obtain valid access tokens for other users due to improper authentication. Authentication against a connected directory service is not sufficiently enforced, which could allow another user's identity to be assumed.4h
