CVE-2024-55488 (GCVE-0-2024-55488)

Vulnerability from cvelistv5 – Published: 2025-01-22 00:00 – Updated: 2026-07-05 14:30 Disputed

Summary

A stored cross-site scripting (XSS) vulnerability in Umbraco CMS v14.3.1 allows attackers to execute arbitrary web scripts or HTML via a crafted payload. NOTE: This has been disputed by the vendor since this potential attack is only possible via authenticated users who have been manually allowed access to the CMS. There was a deliberate decision made not to apply HTML sanitization at the product level.

Severity
