CVE-2026-7884 in Cognos Analytics
Summary
by MITRE • 09/14/2026
IBM Cognos Analytics 12.1.0 through 12.1.3 FP1, and 12.0.4 through 12.0.4 FP2 allows a non-privileged user to edit their given name and surname to include malicious JavaScript code. When an administrator later accesses the user account management panel and views that user's permissions, the malicious JavaScript code is executed. This could result in the cookies from the administrator being compromised.

The vulnerability identified in IBM Cognos Analytics versions 12.1.0 through 12.1.3 FP1 and 12.0.4 through 12.0.4 FP2 represents a classic Stored Cross-Site Scripting (XSS) flaw that exploits the trust relationship between an application's user interface and its administrative components. This security defect allows any authenticated non-privileged user to inject malicious JavaScript payloads by manipulating specific profile fields, namely their given name and surname. The core technical failure lies in the insufficient sanitization of input data during storage rather than just at display time for general users. While standard views might escape or ignore these characters, the administrative interface fails to apply equivalent security controls when rendering user details within the account management panel. Consequently, the malicious script is persisted on the server and subsequently executed in the context of a privileged administrator's session whenever they view the compromised user profile.
From an operational perspective, this vulnerability poses a severe risk to the integrity and confidentiality of the administrative environment. Because the payload executes when an administrator accesses the account management panel, it operates within the security context of that high-privilege account. This enables attackers to perform actions such as stealing session cookies, which can lead to complete session hijacking. Once an attacker possesses a valid administrator cookie, they can impersonate the admin user without needing credentials, potentially gaining full control over the IBM Cognos Analytics instance. This could result in unauthorized access to sensitive business intelligence data, manipulation of reports and dashboards, or further exploitation of underlying system vulnerabilities through administrative functions. The attack vector is particularly dangerous because it requires no special privileges for initiation; any low-level user can trigger a high-impact compromise simply by waiting for an administrator to perform routine account management tasks.
This vulnerability aligns with Common Weakness Enumeration (CWE) ID 79, which describes Improper Neutralization of Input During Web Page Generation known as Cross-site Scripting. Specifically, it falls under the subcategory of Stored XSS where malicious scripts are permanently stored within target servers such as databases or message boards and later executed when users request information from the server. In terms of the MITRE ATT&CK framework, this behavior maps to T1059 Command and Control via Application Layer Protocol if used for beaconing, but more directly relates to T1204 User Execution where a user is tricked into performing an action that leads to code execution. It also correlates with TA0006 Credential Access as the primary goal is often cookie theft or session hijacking to maintain persistent access.
Mitigation strategies must address both immediate remediation and long-term architectural improvements. The most effective solution is for IBM to release a patch that updates the application versions mentioned, ensuring that input validation and output encoding are consistently applied across all administrative interfaces, not just public-facing ones. Administrators should apply these patches immediately upon availability. In the interim, organizations can implement compensating controls such as Web Application Firewalls (WAF) configured with rules to detect and block script injection attempts in profile fields. Additionally, enforcing strict Content Security Policy headers that restrict inline JavaScript execution can significantly reduce the impact of any successful XSS attempt by preventing the browser from executing untrusted scripts unless they are explicitly whitelisted. Regular auditing of user profiles for anomalous content and restricting access to administrative panels through multi-factor authentication also help mitigate the risk of session hijacking resulting from this vulnerability.
