CVE-2026-70813: 
Oracle E-Business Suite vulnerability analysis and mitigation

CVE-2026-70813 is an Improper Access Control vulnerability (CWE-284) in the Oracle Call Center Technology component of Oracle E-Business Suite, specifically affecting the Internal Operations sub-component. It impacts supported versions 12.2.3 through 12.2.15 and was published on August 18, 2026, with a patch released via Oracle's Critical Security Patch Update (CSPU) on August 27, 2026. The vulnerability carries a CVSS v3.1 base score of 8.8 (High), indicating a significant risk to confidentiality, integrity, and availability (Oracle CSPU Aug 2026).

The vulnerability is classified under CWE-284 (Improper Access Control), with an estimated association to CWE-269 (Improper Privilege Management). A low-privileged attacker with network access via HTTP can exploit this flaw in the Internal Operations component of Oracle Call Center Technology without requiring user interaction, making it easily exploitable under standard network conditions. The attack vector is network-based with low complexity and low privilege requirements, enabling a remote authenticated user to escalate their access and compromise the affected system (Oracle CSPU Aug 2026).

Successful exploitation allows a low-privileged attacker to fully take over the Oracle Call Center Technology system, resulting in high impacts to confidentiality, integrity, and availability. An attacker could read sensitive call center and customer data, modify system configurations and operational data, and disrupt service availability. The scope is unchanged, meaning the impact is contained to the vulnerable component itself, but a full system takeover within that scope represents a severe business risk for organizations relying on Oracle E-Business Suite for customer operations (Oracle CSPU Aug 2026).

As of the time of disclosure, there is no public proof-of-concept exploit and no evidence of active in-the-wild exploitation (Oracle CSPU Aug 2026). The EPSS score is approximately 0.0048 (0.48%), indicating a low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been reported.

Oracle has released a patch for CVE-2026-70813 as part of the Critical Security Patch Update (CSPU) for August 2026, available via the Oracle E-Business Suite patch documentation. Organizations should apply the patch immediately for all affected versions (12.2.3–12.2.15). As interim measures, Oracle recommends restricting network access to Oracle Call Center Technology to authorized users only, implementing network segmentation to limit exposure of E-Business Suite components, and monitoring for suspicious activity from authenticated users. Oracle strongly advises against relying on workarounds as a long-term solution (Oracle CSPU Aug 2026).
