Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Commerce Guided Search / Oracle Commerce Experience Manager product of Oracle Commerce (component: Forge). The supported version that is affected is 11.4.0. Easily exploitable vulnerability allows unauthenticated attacker with logon to the infrastructure where Oracle Commerce Guided Search / Oracle Commerce Experience Manager executes to compromise Oracle Commerce Guided Search / Oracle Commerce Experience Manager. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of Oracle Commerce Guided Search / Oracle Commerce Experience Manager. CVSS 3.1 Base Score 7.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

The identified vulnerability resides within the Forge component of Oracle Commerce Guided Search and Oracle Commerce Experience Manager, specifically affecting version 11.4.0. This security flaw represents a significant risk to organizations relying on these platforms for their digital commerce infrastructure. The core issue stems from an architectural weakness that permits unauthenticated access under specific conditions, allowing attackers who have gained logon capabilities to the underlying server infrastructure to compromise the application logic. While the vulnerability technically allows for exploitation without direct authentication to the web application itself, it relies heavily on the attacker having prior network-level or system-level access to the host environment where Oracle Commerce is deployed. This distinction places the attack vector at a local level rather than remote over the internet, which significantly narrows the pool of potential adversaries but increases the severity for those who do achieve initial foothold access.
The technical nature of this flaw enables an attacker with logon privileges on the infrastructure to execute actions that lead to complete compromise of the Oracle Commerce Guided Search and Experience Manager services. The vulnerability is characterized by its ease of exploitation, requiring only low complexity in terms of attack steps once the prerequisite network or system access is established. However, a critical constraint exists: successful exploitation requires human interaction from a user other than the attacker. This social engineering aspect suggests that the vulnerability likely involves a mechanism where an authenticated but non-attacker user must perform a specific action, such as clicking a malicious link, uploading a crafted file, or triggering a specific workflow within the application interface. This dependency on user interaction serves as a partial mitigation against fully automated remote attacks but does not eliminate the risk for insider threats or compromised internal accounts that can be manipulated through phishing or other social engineering tactics.
The operational impact of this vulnerability is severe, classified with a CVSS 3.1 Base Score of 7.8, indicating a High severity rating. The vector string (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) details that while the attack requires local access and user interaction, it results in high impacts across confidentiality, integrity, and availability. A successful takeover of Oracle Commerce Guided Search or Experience Manager grants an attacker comprehensive control over these systems. This can lead to unauthorized modification of product catalogs, manipulation of search algorithms used by customers, theft of sensitive customer data processed through the platform, and disruption of e-commerce operations. The ability to take over these components effectively compromises the integrity of the entire commerce experience, potentially leading to financial loss, reputational damage, and regulatory non-compliance for affected enterprises.
From a classification perspective, this vulnerability aligns with CWE-269, Improper Privilege Management, as it involves an actor gaining privileges they are not authorized to hold by exploiting a flaw in the application's access control logic relative to its infrastructure context. Furthermore, given the requirement for human interaction and potential use of deceptive elements within the commerce interface, this behavior is consistent with ATT&CK technique T1566.002, Phishing: Spearphishing Link, if the user interaction involves clicking a malicious link, or potentially T1078, Valid Accounts, if the attacker leverages compromised credentials to trigger the flaw. The local attack vector also relates to CWE-250, Execution with Unnecessary Privileges, suggesting that the application components may be running with excessive permissions relative to their actual functional requirements.
Mitigation strategies must focus on both technical controls and operational procedures. Since the vulnerability requires logon access to the infrastructure, strict network segmentation is essential to isolate Oracle Commerce servers from less trusted networks or general user workstations. Access control lists should be rigorously enforced to ensure that only authorized administrative accounts can interact with the Forge component directly. Additionally, implementing multi-factor authentication for all system-level and application-level accounts adds a critical layer of defense against credential theft. Organizations should also enforce principle of least privilege by ensuring service accounts do not possess unnecessary local administrator rights. Regular security awareness training is vital to mitigate the human interaction aspect, educating staff on recognizing social engineering attempts that could trigger this vulnerability. Finally, applying vendor-provided patches or updates as soon as they become available remains the most effective long-term solution to eliminate the underlying code flaw entirely.
