CVE-2025-25287

Name of the Vulnerable Software and Affected Versions: Lakeus versions 1.8.0 through 1.3.1 Lakeus versions prior to 1.3.1+REL1.39 Lakeus versions prior to 1.3.1+REL1.42 Lakeus versions prior to 1.4.0

Description: Lakeus is a simple skin made for MediaWiki. It is vulnerable to stored cross-site scripting via malicious system messages, though editing the messages requires high privileges. Those with (editinterface) rights can edit system messages that are improperly handled in order to send raw HTML. In the case of lakeus-footermessage, this will affect all users if the server is configured to link back to this repository. Otherwise, the system messages in themeDesigner.js are only used when the user enables it in their preferences.

Recommendations: For Lakeus versions 1.8.0 through 1.3.1, update to version 1.3.1+REL1.39 or later. For Lakeus versions prior to 1.3.1+REL1.42, update to version 1.3.1+REL1.42 or later. For Lakeus versions prior to 1.4.0, update to version 1.4.0 or later. As a temporary workaround, consider restricting access to the (editinterface) rights to minimize the risk of exploitation. Avoid using the lakeus-footermessage system message until the issue is resolved.
