Security Advisories on d.3one and Weblication CMS Core

11. September 2025

The pentest professionals at usd HeroLab identified cross-site scripting vulnerabilities in Weblication CMS Core and d.3one during web application pentests.

These vulnerabilities enable attackers to execute requests on behalf of other users. We are extremely pleased that the vulnerability in Weblication was rewarded with a bug bounty of €200, which was afterwards donated by usd AG to the Gesellschaft für Freiheitsrechte e.V. (Society for Civil Rights).

The vulnerabilities were reported to the vendor as part of the Responsible Disclosure Policy. Detailed information on the advisories can be found here:
