Okta Access Gateway 2026.10.2 Fixes Authentication Source Verification
Tech GuruQuick Answer
Okta fixes CVE-2026-115546 in Access Gateway 2026.10.2. Inventory appliances and configured authentication sources, upgrade affected systems, validate Admin Console authorization, review relevant sessions where warranted, and retain evidence.
Confirm Scope And Apply The Supported Remediation
What to do now: Inventory Access Gateway releases, authentication sources, active-session controls, Admin Console exposure, administrators, application owners, and change windows. Confirm whether an affected appliance allowed sessions from multiple configured sources; do not infer successful bypass from a user merely having a valid session. Upgrade to Access Gateway 2026.10.2 or later through the supported Okta appliance process. Confirm the appliance release, test authorization boundaries for each configured source, review Admin Console and identity logs where warranted, test protected applications, and retain evidence.

What Changed
Okta fixed authentication-source parameter validation that could allow a user with an active session for one configured source to generate a SAML assertion granting Admin Console access.
What To Validate Now
- Inventory. Inventory Access Gateway releases, authentication sources, active-session controls, Admin Console exposure, administrators, application owners, and change windows.
- Establish applicability. Confirm whether an affected appliance allowed sessions from multiple configured sources; do not infer successful bypass from a user merely having a valid session.
- Remediate. Upgrade to Access Gateway 2026.10.2 or later through the supported Okta appliance process.
- Validate. Confirm the appliance release, test authorization boundaries for each configured source, review Admin Console and identity logs where warranted, test protected applications, and retain evidence.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Okta publishes an 8.1 CVSS v3 score but no textual severity on the advisory. Preserve authentication evidence before invalidating sessions when investigation is justified.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
