Browser script execution via stored image URL
Published May 31, 2023 · Updated Jan 10, 2025
Stored XSS in Dcat-Admin 2.1.3-beta and earlier allows remote authenticated users to execute scripts through a crafted image URL. The logo or another image's file_url accepts injected JavaScript, persists it, and renders the value without sufficient neutralization when a page reloads. A low-privileged account must submit the value and another user must load the affected page; script execution can expose credentials or alter displayed content.
