AnalysisAIv1 – Sep 15, 2026

Unauthenticated attackers with network access to Oracle Access Manager 12.2.1.4.0 and 14.1.2.1.0 can compromise the Authentication Engine component over HTTP, obtaining unauthorized read access to critical data or all data accessible through the product. Oracle rates this CVSS 3.1 8.6 with a scope change (S:C), meaning affected deployments can be leveraged to significantly impact downstream/connected applications that trust OAM identities. At time of analysis there is no public exploit code identified and no CISA KEV listing, but the attack is trivially automatable (AV:N/AC:L/PR:N/UI:N), so internet-exposed OAM consoles and SSO endpoints should be treated as high priority.
