Official Description

The Spotfire Library component of TIBCO Software Inc.'s Spotfire Analyst and Spotfire Server contains an easily exploitable vulnerability that allows a low privileged attacker with network access to execute a Stored Cross Site Scripting (XSS) on the affected system. A successful attack using this vulnerability requires human interaction from a person other than the attacker. Affected releases are TIBCO Software Inc.'s Spotfire Analyst: versions 11.4.7 and below, versions 11.5.0, 11.6.0, 11.7.0, 11.8.0, 12.0.0, 12.0.1, 12.0.2, 12.0.3, and 12.0.4, versions 12.1.0 and 12.1.1 and Spotfire Server: versions 11.4.11 and below, versions 11.5.0, 11.6.0, 11.6.1, 11.6.2, 11.6.3, 11.7.0, 11.8.0, 11.8.1, 12.0.0, 12.0.1, 12.0.2, 12.0.3, 12.0.4, and 12.0.5, versions 12.1.0 and 12.1.1.

Technical Analysis

CVE-2023-26220 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.

From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
