What is CVE-2026-31955?

An authenticated Server-Side Request Forgery (SSRF) vulnerability exists in Xibo, an open-source digital signage platform. Users with DataSet permissions can exploit this flaw to execute arbitrary HTTP requests from the CMS server, potentially accessing sensitive internal or external resources. This includes the ability to scan infrastructure, retrieve local cloud metadata, and interact with unprotected internal services. To mitigate this risk, users must upgrade to version 4.4.1, which addresses the issue. Alternatively, users should revoke DataSet permissions for any untrusted accounts.
