Summary
CVE-2026-34279 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Oracle Enterprise Manager Base Platform. Its CVSS base score is 9.1 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique External Remote Services (T1133); ranked at the 37th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-14 (Permitted Actions Without Identification or Authentication) and IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-34279 is a vulnerability in the Event Management component of the Oracle Enterprise Manager Base Platform product within Oracle Enterprise Manager. The supported versions affected are 13.5 and 24.1. It is classified under CWE-306 (Missing Authentication for Critical Function) and carries a CVSS 3.1 base score of 9.1, with the vector CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H, reflecting high impacts on confidentiality, integrity, and availability.
The vulnerability is easily exploitable by a high privileged attacker who has network access via HTTP. Exploitation allows the attacker to compromise the Oracle Enterprise Manager Base Platform, resulting in a full takeover. While the flaw is contained within the Base Platform, attacks can significantly impact additional products due to a change in scope.
Details on patches and mitigations are available in Oracle's Critical Patch Update advisory for April 2026 at https://www.oracle.com/security-alerts/cpuapr2026.html.

Mitigating Controls (NIST 800-53 r5) AI
Directly mandates unique identification and authentication of users before access to functions requiring identity.
Extends the same authentication requirement to non-organizational users accessing critical functionality.
Requires authentication of services before they can invoke or expose critical functions.
Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.
Access enforcement requires prior authentication before any authorization decision for critical functions.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.
Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.
Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.
Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Mandating authentication requirements for critical functions at the requirements-gathering stage ensures that essential operations are not left unprotected by missing login or verification mechanisms.
Mandating authentication for network services and critical functions stops attackers from invoking sensitive operations without credentials, closing gaps where authentication is absent for important capabilities.
Security engineering principles insist on authentication and authorization for every critical function, eliminating entry points that lack any access control mechanism.
The control explicitly calls for authentication before any critical function is reached, eliminating the possibility of bypassing authentication for high-value operations.
