This vulnerability in Oracle Access Manager's Authentication Engine allows an unauthenticated attacker with network access via HTTP to compromise the product, potentially gaining unauthorized access to critical or all accessible data. The vulnerability affects versions 12.2.1.4.0 and 14.1.2.1.0. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N) indicates network attack vector, low attack complexity, no privileges or user interaction required, scope changed, and high confidentiality impact with no integrity or availability impact. The vulnerability is classified under CWE-306 (Missing Authentication for Critical Function). Oracle's July 2026 Critical Patch Update advisory references this vulnerability among many others but does not explicitly state patch availability or remediation details for it. No known exploits in the wild have been reported.

Successful exploitation can result in unauthorized access to critical data or complete access to all data accessible by Oracle Access Manager. The vulnerability affects confidentiality with no reported impact on integrity or availability. Due to scope change, attacks may also significantly impact additional Oracle products beyond Oracle Access Manager.

Patch status is not yet confirmed — check the Oracle Critical Patch Update advisory at https://www.oracle.com/security-alerts/cpujul2026.html for current remediation guidance. Oracle strongly recommends applying security patches promptly and remaining on actively supported versions. Until official patches or mitigations are confirmed, restrict network access to Oracle Access Manager HTTP interfaces from untrusted sources as a precaution.
