## Overview

The time and filter parameters in Fava prior to v1.22 are vulnerable to reflected cross-site scripting due to the lack of escaping of error messages which contained the parameters in verbatim.

## Affected packages

- `fava < 1.22`

## Remediation

Upgrade to a patched release:

- `fava 1.22`
