Medium 5.4
In plain English
A medium-severity cross-site scripting in quark-auto-save from Cp0204. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 8% of all known vulnerabilities).
Official description
Quark Drive before 0.8.5 contains a stored cross-site scripting vulnerability in the System Configuration page where the template renders push_config key names using Vue.js's v-html directive without escaping. Authenticated attackers can inject HTML or JavaScript payloads as key names through the POST /update endpoint, which are persisted to disk and executed in the browsers of all authenticated users accessing the System Configuration tab, allowing session cookie exfiltration and arbitrary authenticated actions.
