Base vector

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

Name of the Vulnerable Software and Affected Versions Fava versions prior to 1.22

Description The issue concerns reflected cross-site scripting (XSS) due to the lack of escaping of error messages that contain the time and filter parameters in verbatim. This allows for the injection of malicious scripts, potentially leading to unauthorized actions on behalf of the user.

Recommendations For versions prior to 1.22, update to version 1.22 or later to resolve the issue. As a temporary workaround, consider restricting access to the time and filter parameters in error messages until a patch is available. Avoid using the parameters time and filter in a way that could lead to the injection of malicious scripts in error messages.
