| Exploitation Conditions | No special conditions - remote unauthenticated exploitation against affected Oracle Coherence installations (12.2.1.4.0 and 14.1.1.0.0) is possible over HTTP, per CVSS AV:N/AC:L/PR:N/UI:N and Oracle's 'easily exploitable' rating. The one concrete prerequisite is network reachability to a Coherence HTTP-facing service (e.g., a management/REST or Coherence*Extend proxy endpoint); instances that bind these interfaces only to internal/loopback addresses or place them behind firewalls are not directly reachable and thus practically limited. Limiting factors: exploitation requires the vulnerable Core HTTP surface to be exposed and running one of the two affected versions - patched systems or those with the HTTP interface network-isolated are not exploitable. |
| Impact | All hard signals point to genuine high priority rather than an inflated CVSS number: the vector is AV:N/AC:L/PR:N/UI:N with S:U and C:H/I:H/A:H, meaning remote, low-complexity, unauthenticated exploitation with no user interaction and total impact on the target. Oracle explicitly describes it as 'easily exploitable,' reinforcing the low-complexity rating. Tempering factors are that no EPSS score was provided in the input, there is no public exploit identified at time of analysis, and it is not in CISA KEV, so widespread active exploitation is not currently evidenced. One inconsistency to flag: the tags include 'Information Disclosure,' yet the description and CVSS (I:H/A:H plus 'takeover') indicate far more than disclosure - treat the tag as incomplete metadata and rely on the CVSS/description, which describe full compromise. Net: unauthenticated network-facing full-takeover flaws in middleware are routinely reverse-engineered from patches within days to weeks, so patch urgency is high despite the current absence of a public POC. |
| Exploit ScenarioDerived | An attacker who can reach a Coherence HTTP-facing port on the network sends a single crafted request to the exposed Core interface and, without any credentials or user interaction, gains control of the Coherence process - enabling data theft, tampering, and service disruption. Because Coherence often runs with application-level trust inside a WebLogic cluster, that foothold can be pivoted toward backend data and adjacent middleware. No public exploit code has been identified at time of analysis, but the low attack complexity makes weaponization straightforward once patch details are studied. |

Alert meAnalysisAIv1 – Jul 21, 2026
Full remote takeover of Oracle Coherence (Oracle Fusion Middleware, Core component) versions 12.2.1.4.0 and 14.1.1.0.0 is possible by an unauthenticated attacker sending crafted traffic over HTTP, per Oracle's July 2026 Critical Patch Update. The flaw carries a CVSS 3.1 base score of 9.8 with full confidentiality, integrity, and availability impact and is rated by Oracle as 'easily exploitable,' meaning no special skill or configuration is needed. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the network-reachable, no-authentication profile makes it a high-priority patch target.
RemediationAI
Apply the patch from the Oracle July 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpujul2026.html), which is the primary and authoritative fix for the affected 12.2.1.4.0 and 14.1.1.0.0 releases; Oracle distributes these as CPU bundle patches rather than a single renamed version, so identify the exact patch number for your Coherence/WebLogic release in that advisory. Apply patch per vendor advisory as the specific fix; a discrete renamed patched version is not independently confirmed from the input. Until patching is complete, reduce exposure by restricting network access to Coherence HTTP-facing endpoints (management, REST, and Coherence*Extend proxy ports) to trusted management networks via firewall/ACLs, and place any internet-exposed instance behind a reverse proxy or VPN - the trade-off is that legitimate remote management or extend clients on those paths will lose connectivity and must be allow-listed. If unsafe deserialization is the mechanism (unconfirmed, CWE N/A), enforcing Coherence/WebLogic serialization filters (JEP 290 allow-lists) can further limit reachability, at the cost of potentially breaking clients that rely on Java-serialized payloads.

Technical ContextAI · show details
Oracle Coherence is an in-memory data grid and distributed caching/computation platform bundled with Oracle Fusion Middleware, commonly used to scale Java (WebLogic) applications by clustering data across nodes. The vulnerability sits in the 'Core' component and is reachable over HTTP, which points at Coherence's management/extend or REST-facing interfaces rather than internal cluster (TCMP) traffic. Oracle did not assign a CWE (listed N/A), so the precise root-cause class is unconfirmed; however, prior Coherence 'takeover via HTTP' issues have historically stemmed from unsafe deserialization of untrusted data, and the full C/I/A compromise here is consistent with a remote code execution or object-injection class flaw. The affected CPE is cpe:2.3:a:oracle_corporation:oracle_coherence, covering the Coherence application component specifically.

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 and 14.1.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Coherence. Successful attacks of this vulnerability can result in takeover of Oracle Coherence. CVSS 3.1 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
Executive ViewAI
Oracle Coherence (versions 12.2.1.4.0 and 14.1.1.0.0), a critical Oracle Fusion Middleware component, contains a vulnerability enabling unauthenticated attackers to achieve complete system takeover (CVSS 9.8) via a single HTTP request-no credentials or special skills required. Organizations running affected versions face immediate risk of data theft, ransomware deployment, and service outages. With no vendor-released patch available, emergency network isolation is essential to prevent full infrastructure compromise.
Network isolation via firewall segmentation and ACLs (restrict HTTP access to Coherence instances from external networks and untrusted subnets); comprehensive traffic logging to detect exploitation signatures and anomalous access patterns; intrusion prevention system or WAF rules tuned to block attack traffic until permanent patching is feasible; continuous monitoring of affected systems for behavioral anomalies indicating compromise.
