Vulnerability Details
The official description of CVE-2025-50018 states that it involves improper neutralization of input during web page generation, allowing stored XSS vulnerabilities. The CVSS score is 5.9, indicating a medium severity level, and the vulnerability affects Tealium Tealium versions from n/a through 2.1.20. The underlying weakness is classified under CWE-79.
Technical Analysis
The root cause of this vulnerability stems from inadequate input validation during the generation of web pages in Tealium Tealium. Attackers may leverage this vulnerability by injecting malicious scripts into web pages, which are then executed in the context of users’ browsers. The attack vector is network-based, and the complexity is low, requiring high privileges and user interaction.
The confidentiality, integrity, and availability impacts are all classified as low, meaning that while the exploitation may not lead to catastrophic failures, it can still compromise user data and application functionality.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access and manipulation of user data through stored XSS attacks. The blast radius can extend to all users interacting with the affected application. Given that this vulnerability falls within the medium severity category, organizations should assess their exposure and prioritize remediation efforts accordingly.
As CVE-2025-50018 is not included in the KEV catalog, it may not be actively exploited in the wild. However, organizations should remain vigilant and incorporate monitoring strategies to detect potential exploitation attempts.
