CVE-2026-115546 · Severity: high · CVSS 8.1 · Published 2026-10-23

Okta Access Gateway is an authentication appliance that controls access to corporate applications. An attacker with an active session can manipulate which authentication method is used during sign-on, potentially obtaining a SAML credential that grants access to the admin console. This could lead to unauthorized administrative access and full compromise of the gateway.
