CVE-2026-101504 in Trusted Answer Search
Summary
by MITRE • 10/21/2026
Vulnerability in Oracle Trusted Answer Search (component: Application expert UI). The supported version that is affected is 26.1. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Trusted Answer Search. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Trusted Answer Search, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Trusted Answer Search accessible data as well as unauthorized update, insert or delete access to some of Oracle Trusted Answer Search accessible data. CVSS 3.1 Base Score 7.6 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N).

Analysis

The vulnerability identified in Oracle Trusted Answer Search, specifically within the Application expert UI component of version 26.1, represents a significant security risk due to its potential for unauthorized data access and modification. This flaw is classified as an easily exploitable issue that allows attackers with low privileges and network access via HTTP to compromise the system. The presence of this vulnerability indicates a failure in proper input validation or authorization checks within the user interface layer, which serves as the primary interaction point for users managing trusted answer configurations. Because the component handles sensitive security policies, any breach here can have cascading effects on the broader Oracle ecosystem, leading to what is described as a scope change where attacks impact additional products beyond just Trusted Answer Search itself.
From a technical perspective, this vulnerability aligns with CWE-20 Improper Input Validation and potentially CWE-862 Missing Authorization, depending on whether the exploit relies on tricking users into performing actions or bypassing access controls directly. The requirement for human interaction suggests that part of the exploitation chain may involve social engineering elements, such as a Cross-Site Scripting scenario where an attacker tricks a legitimate user into clicking a malicious link or submitting crafted data through the UI. This aligns with MITRE ATT&CK technique T1059 Command and Control via Application Layer Protocol if used for further compromise, or more likely T1204 User Execution if it involves tricking users into running malicious content. The low attack complexity indicates that once a user is engaged, the technical steps to exploit the flaw are straightforward, requiring no specialized knowledge beyond basic web interaction capabilities.
The operational impact of this vulnerability is severe, primarily affecting confidentiality and integrity while leaving availability largely unaffected according to the CVSS 3.1 base score of 7.6. Successful exploitation can lead to unauthorized access to critical data stored within Oracle Trusted Answer Search. This includes sensitive security policies, configuration details, and potentially credentials or keys associated with trusted answers. Furthermore, attackers gain the ability to perform unauthorized updates, inserts, or deletes on accessible data. This integrity violation allows an attacker to alter trust relationships, effectively undermining the core purpose of the application which is to manage secure communication channels and authentication mechanisms. The scope change noted in the description implies that compromising this component could allow lateral movement into other Oracle products connected through shared infrastructure or identity management systems, amplifying the blast radius significantly beyond a single application failure.
Mitigation strategies must focus on both immediate remediation and long-term architectural improvements. Oracle should release an updated version of Trusted Answer Search 26.1 that patches the specific input validation flaws in the Application expert UI. In the interim, administrators should restrict network access to this component by placing it behind a Web Application Firewall configured with strict rules against common injection patterns and unauthorized API calls. Access controls must be reviewed to ensure that low-privileged users do not have direct HTTP access to sensitive administrative functions without additional multi-factor authentication or approval workflows. Additionally, implementing Content Security Policy headers can help mitigate potential cross-site scripting vectors if the vulnerability involves script execution within the browser context. Regular security audits and penetration testing of the UI components are recommended to identify similar weaknesses before they can be exploited in production environments.
