Deeper analysis

MachForm versions up to 19 contain an authenticated stored cross-site scripting vulnerability tracked as CVE-2024-37764. The flaw is classified under CWE-79 and carries a CVSS 3.1 score of 5.4, reflecting network attack vector, low attack complexity, low-privileged access, required user interaction, and changed scope with limited confidentiality and integrity consequences.

An authenticated user can supply malicious input that is stored and later rendered in other users' browsers, enabling the attacker to execute scripts in the context of the affected application. This can result in limited data exposure or unauthorized actions within the application's scope.

Public references consist of a GitHub repository that documents the issue, but no vendor advisory or patch information is provided in the available sources. The associated EPSS score has remained flat at 0.0714 with no observed increase after disclosure.
