CVE-2026-0949 is a stored Cross-site Scripting (XSS) vulnerability affecting EnterpriseDB PostgreSQL Enterprise Manager (PEM) versions prior to 9.8.1. This vulnerability allows users with access to the Manage Charts menu to inject arbitrary JavaScript when creating a new chart. The injected script will execute whenever another user accesses the chart, potentially leading to unauthorized actions or data exposure.
The severity level for this vulnerability is categorized as medium, with a CVSS score of 6.5. This rating indicates a moderate risk, primarily due to the potential for unauthorized script execution affecting users with access to the charts. Organizations utilizing affected versions of the product should take note of this vulnerability and assess the potential impacts on their systems.
Currently, no known exploits have been reported in the wild, and the vulnerability has not been listed in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant and prioritize patching to prevent any future exploitation. Given the nature of XSS vulnerabilities, attackers may leverage this weakness for various malicious purposes.
Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability. Maintaining up-to-date software versions is crucial for the security of web applications and the protection of sensitive data.
Vulnerability Details
The vulnerability allows users with access to the Manage Charts menu to inject JavaScript when creating a new chart, which is executed by any user accessing that chart. By default, only superusers and users with pem_admin or pem_super_admin privileges can access this menu.
The CVSS 3.1 vector string is CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N, indicating that the attack vector is network-based, with low complexity, and requires high privileges but does not require user interaction. The impacts on confidentiality and integrity are high, while availability remains unaffected.
This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'). Organizations should review their configurations and apply necessary security measures.
Technical Analysis
The root cause of this vulnerability lies in the improper sanitization of user input within the Manage Charts functionality of PEM. Attackers may exploit this vulnerability by crafting malicious charts that include harmful scripts. When other users access these charts, the scripts execute in their browsers, leading to potential data theft or unauthorized actions.
The attack vector is network-based, which means that an attacker can exploit this vulnerability remotely without physical access to the target system. The attack complexity is low, allowing malicious users to exploit this vulnerability easily with high privileges required to access the Manage Charts menu.
No user interaction is necessary to trigger the vulnerability, as the malicious scripts execute automatically upon accessing the affected charts. The confidentiality and integrity impacts are significant due to the potential for sensitive information exposure and the ability to manipulate data.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data and potential manipulation of the application’s functionalities. The vulnerability's blast radius is notable, especially for enterprises relying on PEM for managing critical chart data. If exploited, attackers could execute arbitrary scripts, which could lead to further compromises within the affected environment.
Given the medium CVSS score of 6.5, organizations should address this vulnerability in their priority patch cycle. The potential for exploitation, while not currently observed, exists due to the nature of stored XSS vulnerabilities. The urgency for remediation is heightened by the need to protect user data and maintain the integrity of the application.
Regular updates and security assessments are critical components of a robust security posture. Organizations should also consider implementing additional security measures, such as input validation and output encoding, to mitigate risks associated with future vulnerabilities.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerability affects all versions of PostgreSQL Enterprise Manager prior to 9.8.1. Organizations should ensure they are running the latest version to avoid this and other vulnerabilities.
Mitigation & Remediation
Organizations should apply the latest patches provided by EnterpriseDB to remediate this vulnerability. The recommended version to upgrade to is 9.8.1 or later. In cases where immediate patching is not possible, organizations should implement strict access controls to the Manage Charts menu, limiting access only to trusted administrators.
Additional network controls, such as web application firewalls, should be considered to help detect and block potential XSS attacks. Regular security assessments and monitoring for unusual activity can also aid in identifying attempts to exploit this vulnerability.
For further insights on security practices, organizations may refer to our guide on application security assessment which can help in identifying potential vulnerabilities.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should review logs for unusual script executions or changes made to charts without proper authorization. Monitoring for behavioral anomalies in user activity, especially from users with access to the Manage Charts menu, is essential.
Network signatures that identify XSS attack patterns can be useful in proactively detecting and preventing such exploitation attempts.
