Deeper analysis
The vulnerability is a reflected cross-site scripting flaw (CWE-79) present in the Microweber GitHub repository prior to version 1.2.18. It carries a CVSS 3.1 score of 6.1 with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, indicating that untrusted input can be reflected back to a victim without authentication.
An unauthenticated remote attacker can craft a malicious URL or request that, when clicked by a user, causes arbitrary JavaScript to execute in the victim's browser context. Successful exploitation can lead to limited theft of session data or unauthorized actions performed on behalf of the victim due to the changed scope and partial impact on confidentiality and integrity.
The linked GitHub commit c51285f791e48e536111cd57a9544ccbf7f33961 and the associated huntr.dev report document the remediation, showing that the flaw was resolved by sanitizing reflected output; administrators are advised to upgrade to Microweber 1.2.18 or newer.
