Deeper analysis
The vulnerability is a stored cross-site scripting flaw (CWE-79) in the Microweber content management system, present in all versions prior to 1.2.12. It carries a CVSS 3.1 score of 5.4 and is triggered when user-supplied input is persisted and later rendered without adequate output encoding.
An authenticated user with low privileges can supply crafted markup that is stored on the server and subsequently executed in the browsers of other users who view the affected page. Because the attack occurs over the network with only a required user interaction and changes scope, successful exploitation can result in limited theft of session tokens or display of attacker-controlled content within the application origin.
The maintainers resolved the issue in commit fc9137c031f7edec5f50d73b300919fb519c924a, which is included in release 1.2.12; organizations should apply the update or back-port the change to neutralize the injection vectors. The associated EPSS score has remained flat at 0.0626 with no material increase since disclosure.
