Deeper analysis
CVE-2022-1439 is a reflected cross-site scripting vulnerability in the Microweber content management system, affecting versions prior to 1.2.15. The flaw resides in the demo.microweber.org/demo/module/ endpoint and permits an attacker to inject and execute arbitrary JavaScript in the context of a victim user who visits a crafted URL.
An unauthenticated remote attacker can exploit the issue by supplying a malicious payload that is reflected back to the victim; successful exploitation allows the attacker to run JavaScript with the privileges of the targeted user, potentially leading to session hijacking or other client-side actions. The CVSS vector indicates the attack requires user interaction and results in limited confidentiality and integrity impact.
Public references point to a fix merged in commit ad3928f67b2cd4443f4323d858b666d35a919ba8, which addresses the input handling flaw; administrators should upgrade to Microweber 1.2.15 or later. The associated EPSS score has remained in the 0.43–0.46 range without a pronounced post-disclosure increase.
