Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVE-2025-54384

Medium
6.3/10

Summary

CKAN is an open-source DMS (data management system) for powering data hubs and data portals. In versions prior to 2.10.9 and 2.11.x prior to 2.11.4, the "helpers.markdown_extract()" function did not perform sufficient sanitization of input data before wrapping it in an HTML literal element. This helper is used to render user-provided data on dataset, resource, organization, or group pages (plus any page provided by an extension that uses that helper function), leading to a potential XSS vector.

CWE-79 - Cross Site Scripting

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
