Can you explain this vulnerability to me?
CVE-2026-45231 is a stored cross-site scripting (XSS) vulnerability found in DumbAssets versions up to 1.0.11. It occurs because certain asset fields such as name, description, modelNumber, serialNumber, and tags are stored without server-side sanitization and are rendered using innerHTML without client-side escaping.
Attackers can exploit this by creating or updating assets with malicious HTML or JavaScript payloads via the asset API endpoints. When other users view the asset list, these scripts execute in their browsers.
If the Content-Security-Policy is disabled, the injected scripts can make unrestricted connections to internal network services, increasing the potential impact.
How can this vulnerability impact me? :
This vulnerability can lead to arbitrary script execution in the browsers of users who view the affected asset list. This can result in theft of user credentials, session hijacking, or unauthorized actions performed on behalf of the user.
Additionally, if Content-Security-Policy is disabled, the malicious scripts can make unrestricted connections to internal network services, potentially exposing sensitive internal resources or data.
