CVE-2026-45228 Cp0204 CVE debrief

CVE-2026-45228 is a stored cross-site scripting vulnerability in Quark Drive before 0.8.5. The vulnerability exists 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. This allows for session cookie exfiltration and arbitrary authenticated actions.

The CVSS score for this vulnerability is 5.1, indicating a medium severity.

Defensive priority

Medium priority should be given to patching Quark Drive versions before 0.8.5, as this vulnerability requires authentication but could lead to session cookie exfiltration and arbitrary authenticated actions.

Recommended defensive actions

  • Patch Quark Drive to version 0.8.5 or later
  • Restrict access to the System Configuration page to only necessary users
  • Monitor for suspicious activity on the System Configuration tab
  • Consider implementing additional security measures such as input validation and output encoding
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
