| Exploitation Conditions | Exploitation requires network access to Oracle Coherence over TCP and, critically, human interaction from a person other than the attacker (CVSS UI:R) - for example a legitimate user or operator being lured into triggering the malicious action; without that interaction the attack does not succeed, which is the primary limiting factor. No authentication is required (PR:N), attack complexity is low (AC:L), and it applies to the supported affected versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0. The scope change (S:C) means a successful attack can reach beyond Coherence into additional co-deployed products. Availability is not impacted (A:N); the impact is confidentiality and integrity of Coherence-accessible data. |
| Impact | The signals are mostly aligned toward high priority but with one important limiter. CVSS 3.1 is 9.3 driven by AV:N, AC:L, PR:N (unauthenticated), a scope change (S:C), and High confidentiality and integrity impact - a serious, easily exploitable network flaw. The key discriminator is UI:R: exploitation requires human interaction from a person other than the attacker, so this is not a fully autonomous, wormable network exploit; it needs a victim to be lured into an action. No EPSS score, no CISA KEV listing, and no POC were provided, so there is no public exploit identified at time of analysis and no evidence of active exploitation. Net: treat as high-priority patching (unauthenticated + scope change + High C/I in enterprise middleware), but the user-interaction requirement and absence of exploitation evidence argue this is a patch-in-cycle CVE rather than an emergency zero-day. Note the vendor-tagged 'Authentication Bypass' is not independently corroborated by a CWE. |
| Exploit ScenarioDerived | An attacker with only network TCP access to an Oracle Coherence deployment crafts a malicious request or link and induces a legitimate user or operator to trigger it, requiring no attacker credentials. Because the vulnerability crosses a security scope, the attacker gains unauthorized read and modify access to critical Coherence data and can impact adjacent Fusion Middleware products. No public POC was provided, so this scenario is derived from the CVSS vector rather than an observed exploit. |

Alert meAnalysisAIv1 – Jul 21, 2026
Unauthorized data compromise in Oracle Coherence (Oracle Fusion Middleware Core component) lets an unauthenticated network attacker read and modify all Coherence-accessible data and impact additional products through a scope change, provided a legitimate user is tricked into a required interaction. It affects supported versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0, carries an Oracle CVSS 3.1 base score of 9.3, and has no public exploit identified at time of analysis. Fixes ship in the Oracle July 2026 Critical Patch Update.
RemediationAI
Apply the Oracle July 2026 Critical Patch Update for the affected Coherence releases - patch available per vendor advisory at https://www.oracle.com/security-alerts/cpujul2026.html; Oracle CPUs deliver version-specific patch sets for each listed release (12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, 15.1.1.0.0), and no separate standalone fix version was specified in the source data, so follow the CPU patch mapping for your exact build. As compensating controls until patched, restrict network reachability of Coherence cluster and management TCP listeners to trusted hosts only via network segmentation/firewall ACLs (trade-off: may break cross-node or client connectivity if ports are shared), and because exploitation requires human interaction, reinforce operator/admin awareness and limit who can be induced to trigger the affected action. Do not expose Coherence ports to untrusted networks or the internet.

Technical ContextAI · show details
Oracle Coherence is a distributed in-memory data grid used within Oracle Fusion Middleware for caching, clustering, and scalable state management behind many enterprise Java (WebLogic/Fusion) deployments. The single CPE cpe:2.3:a:oracle_corporation:oracle_coherence:*:*:*:*:*:*:*:* confirms the affected component is the Coherence application layer (Core). No CWE was assigned by the source, but the supplied tag 'Authentication Bypass' plus the CVSS vector (PR:N with a scope change) points to a flaw that lets untrusted network input reach a trusted processing context - consistent with unsafe handling of attacker-influenced data or requests within the Coherence cluster/TCP listener rather than a memory-safety bug (availability impact is None).

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 unauthenticated attacker with network access via TCP to compromise Oracle Coherence. Successful attacks require human interaction from a person other than the attacker and 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 9.3 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N).
Executive ViewAI
Oracle Coherence (Fusion Middleware Core) versions 12.2.1.4.0 through 15.1.1.0.0 contain a critical vulnerability allowing unauthenticated attackers to read and modify all cached data while potentially compromising interconnected Oracle systems. Any organization deploying these versions faces direct risk of data breach and lateral movement to business-critical applications.
Apply vendor patch: Oracle July 2026 Critical Patch Update. If immediate patching is not feasible, implement strict network access controls to Coherence ports (typically 9000-9500) using allow-lists, restrict Coherence remote access to essential services only, and enable enhanced audit logging on all Coherence operations to detect anomalous access patterns.
