Critical

Base vector

AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: zonote versions through 0.4.0

Description: The issue allows for Cross-Site Scripting (XSS) via a crafted note, which can result in Remote Code Execution. This is possible because nodeIntegration in webPreferences is set to true.

Recommendations: For versions through 0.4.0, update to a version where nodeIntegration in webPreferences is set to false or apply other mitigations to prevent XSS attacks. As a temporary workaround, consider disabling the nodeIntegration in webPreferences until a patch is available. Restrict access to crafted notes to minimize the risk of exploitation.
