Technical Summary
CVE-2026-46866 affects Oracle Enterprise Manager Base Platform component Agent Next Gen in versions 13.5 and 24.1. It is an easily exploitable vulnerability that allows unauthenticated remote attackers over HTTPS to cause a hang or repeated crash (complete denial of service) and unauthorized modification (update, insert, delete) of some accessible data. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H, indicating network attack vector, low attack complexity, no privileges or user interaction required, unchanged scope, no confidentiality impact, limited integrity impact, and high availability impact. Oracle has published this vulnerability in its June 2026 Critical Security Patch Update advisory and strongly recommends applying the patches without delay. No explicit patch version or remediation level is stated in the advisory content, but the update contains targeted security fixes including this vulnerability.
Potential Impact
Successful exploitation can result in complete denial of service of the Oracle Enterprise Manager Base Platform by causing hangs or frequent crashes. Additionally, attackers can gain unauthorized ability to update, insert, or delete some data accessible via the platform, impacting data integrity. There is no confidentiality impact reported. The vulnerability is exploitable remotely without authentication over HTTPS, increasing the risk exposure.
Mitigation Recommendations
Oracle strongly recommends applying the June 2026 Critical Security Patch Update, which includes fixes for this vulnerability. Until patches are applied, risk may be reduced by blocking network protocols required for exploitation or by removing unnecessary privileges or access to vulnerable components from users who do not need them. These mitigations may impact application functionality. Customers should consult the Oracle advisory at https://www.oracle.com/security-alerts/cspujun2026.html for detailed patch availability and installation instructions. Patch status is not explicitly confirmed in the advisory; therefore, verify current remediation guidance from Oracle.
