# POC Description Source Link Shenlong Link
1 Mailcow-dockerized before 2022-09a uses a vulnerable version of Swagger UI (before 4.11.1) that is affected by a DOM-based Cross-Site Scripting (XSS) vulnerability. When a user accesses the Swagger documentation with a crafted configUrl or url parameter containing JavaScript payloads, arbitrary code execution can occur in the user's browser. This allows attackers to steal cookies, session data, or execute actions on behalf of the victim by enticing them to open a malicious Swagger UI link. https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2022/CVE-2022-39258.yaml POC Details
