AI Analysis

Impact

A flaw in Oracle Coherence allows an attacker with low privileges who can reach the system over HTTP to trigger a partial denial of service. The weakness leads to availability impact only, without exposing sensitive data or enabling arbitrary code execution.

Affected Systems

Oracle Coherence (Oracle Fusion Middleware). Vulnerable versions include 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0.

Risk and Exploitability

The vulnerability has a CVSS v3.1 base score of 4.3, reflecting a moderate risk confined to availability. The EPSS score is less than 1%, indicating a very low probability of exploitation. It is not listed in CISA KEV. Exploitation requires only network connectivity to the vulnerable HTTP endpoints and does not rely on elevated privileges or specialized tools.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the Oracle CPU July 2026 patch for Oracle Coherence to update affected installations to a fixed version, correcting the Resource Exhaustion flaw labeled CWE‑400.
  • Enforce strict access control and network segmentation around Coherence HTTP endpoints to limit the potential attack surface and reduce the risk of denial‑of‑service attempts.
  • If the HTTP management interface is not required, disable it or block its port, further restricting potential resource‑exhaustion vectors.
