| Exploitation Conditions | Exploitation requires network access to Oracle Coherence's HTTP interface and a low-privileged account on/against the target (CVSS PR:L, AV:N, AC:L, UI:N) - it is NOT fully unauthenticated, so the attacker must already possess some low-level credential or foothold that can send HTTP requests to Coherence. The affected deployment must be one of the supported versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 or 15.1.1.0.0 with the Core component's HTTP endpoint reachable. Limiting factors that reduce real-world risk: the Coherence management/cluster HTTP interface is frequently deployed on internal/segmented networks rather than internet-facing, and a valid low-privilege account is needed; the scope change (S:C) is what elevates the consequence because impact can extend to additional products beyond Coherence. Availability is not impacted (A:N), so this cannot be used directly for denial-of-service. |
| Impact | The signals converge on genuine high priority: CVSS 3.1 is 9.6 with an easily exploitable network vector (AV:N/AC:L), only low privileges required (PR:L), no user interaction (UI:N), and a scope change (S:C) that Oracle explicitly says may significantly impact additional products. Impact is on confidentiality and integrity (C:H/I:H) but not availability (A:N), so this is a data-exposure and data-tampering issue rather than a denial-of-service. Counterbalancing factors: it is NOT in CISA KEV (no confirmed active exploitation) and no POC is referenced, so there is no evidence of exploitation in the wild yet. EPSS is not provided in the input, so probabilistic exploitation likelihood cannot be quantified here. The combination of low complexity, low privilege, and scope change means that once an exploit surfaces this would be attractive for lateral movement - treat as urgent despite the absence of KEV/POC signals. |
| Exploit ScenarioDerived | A low-privileged user who can reach the Oracle Coherence HTTP interface on the network sends a crafted HTTP request that bypasses authorization controls, then reads or modifies arbitrary Coherence-managed data across the cluster. Because of the scope change, the attacker leverages this foothold to affect additional connected products/services beyond Coherence. No public exploit is identified at time of analysis, and no user interaction is required (UI:N), so the attack requires only network access and a low-privilege account. |

Alert meAnalysisAIv1 – Jul 21, 2026
Authentication bypass and data compromise in Oracle Coherence (Oracle Fusion Middleware Core component) versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0 allows a low-privileged, network-adjacent attacker to read, create, delete or modify all Coherence-accessible data over HTTP. Because the flaw carries a scope change, successful exploitation can significantly impact additional products beyond Coherence itself, yielding a CVSS 3.1 score of 9.6. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the low attack complexity and low privilege requirement make it a high-priority patch item.
RemediationAI
Apply the patches from the Oracle Critical Patch Update of July 2026 (https://www.oracle.com/security-alerts/cpujul2026.html) - patch available per vendor advisory; Oracle CPUs ship fixes as quarterly patch bundles/PSUs for each affected line (12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, 15.1.1.0.0), and the exact patched build numbers should be pulled from the CPU matrix and My Oracle Support. Until patching is complete, reduce exposure of the Coherence HTTP management/cluster endpoints: restrict network access to Coherence management interfaces to trusted administrative hosts via firewall/network segmentation (side effect - breaks remote management tooling that relies on those endpoints), disable or lock down any Coherence REST/management HTTP services that are not required (side effect - loss of HTTP-based monitoring/administration), and tighten authentication and role assignments so that low-privilege accounts cannot reach the vulnerable interface. Because the flaw involves a scope change, also review and isolate downstream products that trust the Coherence cluster.

Technical ContextAI · show details
Oracle Coherence is Oracle's distributed in-memory data grid, used to cache and share application state across clustered JVMs and commonly deployed as part of Oracle Fusion Middleware and WebLogic-based stacks. The vulnerability resides in the Core component and is exposed over HTTP, indicating the Coherence management/cluster HTTP interface rather than the native TCMP cluster protocol. Oracle does not assign a CWE (CWE: N/A), but the vendor tag 'Authentication Bypass' together with the CVSS confidentiality and integrity impacts (C:H/I:H, A:N) points to a broken access-control / improper authentication root cause (CWE-287/CWE-284 class) that lets an attacker act with more authority than their assigned privilege level.

DescriptionCVE.org
Vulnerability in the Oracle Coherence product of Oracle Fusion Middleware (component: Core). Supported versions that are affected are 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Coherence. While the vulnerability is in Oracle Coherence, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Coherence accessible data as well as unauthorized access to critical data or complete access to all Oracle Coherence accessible data. CVSS 3.1 Base Score 9.6 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N).
Executive ViewAI
Oracle Coherence installations (versions 12.2.1.4.0 through 15.1.1.0.0) are vulnerable to an authentication bypass allowing attackers to remotely access, modify, or delete all cached business-critical data, with cascading impact across dependent Oracle products. This vulnerability poses immediate risk to data confidentiality and integrity across systems relying on Coherence for data management. With no vendor patch currently available, organizations must implement interim protective measures immediately.
No vendor-released patch identified at time of analysis. Implement interim mitigations: (1) restrict HTTP access to Coherence through network-layer firewall segmentation; (2) enforce application-layer authentication and authorization validation independent of Coherence; (3) deploy comprehensive access logging and behavioral anomaly detection for all data operations; (4) evaluate temporary containerized or isolated deployment architectures to minimize network exposure; (5) maintain continuous monitoring of Oracle security advisories for patch releases and maintain upgrade readiness.
