CVE-2026-34576 is a Server-Side Request Forgery (SSRF) vulnerability in the gitroomhq postiz-app prior to version 2.21.3. The vulnerable endpoint POST /public/v1/upload-from-url accepts a user-supplied URL and fetches it server-side without proper SSRF protections, relying only on a weak file extension check that can be bypassed. An authenticated API user can exploit this to access internal network resources, cloud instance metadata, and other internal services. The issue has been patched in version 2.21.3.
