Xibo is an open source digital signage platform with a web content management system and Windows display player software. Prior to 4.4.2, a vulnerability chain consisting of Stored XSS and Iframe Sandbox escape in the Xibo CMS allows users with DataSet permissions to use the Data Connector functionality to craft messages which escape the sandbox and facilitate XSS. Exploitation of the vulnerability is possible on behalf of an authorized user who has both of the following privileges, which are not granted to non-admins as standard: Include "Add DataSet" button to allow for additional DataSets to be created independently to Layouts Users should upgrade to version 4.4.2 which fixes this issue. Upgrading to a fixed version is necessary to remediate. Users unable to upgrade should revoke such privileges from users they do not trust.

CVE-2026-42141 is a Server-Side Request Forgery (SSRF) vulnerability in the Xibo CMS digital signage platform prior to version 4.4.1. Authenticated users with Library upload permissions can exploit this flaw to make arbitrary HTTP requests from the CMS server to internal or external network resources. This can lead to scanning internal infrastructure, accessing cloud metadata endpoints such as AWS IMDS, interacting with unauthenticated internal services, or exfiltrating data. The vulnerability has a high severity with a CVSS score of 7.7 and is fixed in version 4.4.1. The vendor manages remediation for this cloud-hosted service.

CVE-2026-31956 is an authorization bypass vulnerability in xibo-cms versions prior to 4.4.1. Authenticated users with certain privileges can manually construct URLs to preview campaigns or regions and export reports belonging to other users. This issue allows unauthorized access to data within the application. The vulnerability is fixed in version 4.4.1.

Xibo is an open source digital signage platform with a web content management system and Windows display player software. An authenticated Server-Side Request Forgery (SSRF) vulnerability in versions prior to 4.4.1 allows users with DataSet permissions to make arbitrary HTTP requests from the CMS server to internal or external network resources. This can be exploited to scan internal infrastructure, access local cloud metadata endpoints (e.g., AWS IMDS), interact with internal services that lack authentication, or exfiltrate data. Exploitation of the vulnerability is possible on behalf of an authorized user who has both of the following privileges, which are not granted to non-admins as standard: Include "Add DataSet" button to allow for additional DataSets to be created independently to Layouts. Users should upgrade to version 4.4.1 which fixes this issue. Upgrading to a fixed version is necessary to remediate. Users unable to upgrade should revoke such privileges from users they do not trust.

A stored Cross-Site Scripting (XSS) vulnerability exists in xibo-cms versions prior to 4.4.1. An authenticated user with notification creation permissions can inject arbitrary JavaScript into notification bodies. When such a notification is set as an "interrupt," the script executes automatically in the browser of any targeted user upon login without requiring user interaction. This vulnerability requires privileges that are not granted to non-admin users by default. The issue is fixed in version 4.4.1.

Xibo CMS versions 1.7 through 4.4.0 contain an SQL injection vulnerability in the API routes responsible for filtering DataSets. This flaw allows an authenticated user with specific privileges to inject malicious SQL commands via the API filter parameter, potentially leading to unauthorized data access and modification. The issue is fixed in version 4.4.1. Customers hosting CMS with Xibo Signage have been patched for supported versions. Upgrading to version 4.

Xibo is an open source digital signage platform with a web content management system (CMS). Versions 4.3.0 and below contain a Remote Code Execution vulnerability in the CMS Developer menu's Module Templating functionality, allowing authenticated users with "System -> Add/Edit custom modules and templates" permissions to manipulate Twig filters and execute arbitrary server-side functions as the web server user. This issue is fixed in version 4.3.1. To workaround this issue, use the 4.1 and 4.2 patch commits.
