Security readout for executives and security teams
Plain-English summary
Quark Drive versions before 0.8.5 can store malicious content in system configuration names. When another authenticated user opens the System Configuration tab, that content can run in their browser. This can support unauthorized actions within the victim's session.
Executive priority
Treat as a near-term remediation for affected internal or customer-facing deployments. It is not marked exploited, but authenticated stored XSS can undermine administrator trust boundaries and user sessions.
Technical view
The issue is stored XSS in quark-auto-save before 0.8.5. The System Configuration page renders push_config key names with Vue v-html without escaping. An authenticated attacker can persist malicious key names through POST /update, which execute when authenticated users view that tab.
Likely exposure
Exposure is limited to Cp0204 quark-auto-save deployments before 0.8.5 where authenticated users can modify system configuration through the update endpoint.
Exploitation context
The bundle reports no KEV listing and provides no evidence of active exploitation. Exploitation requires authenticated access and user interaction by another authenticated user viewing the affected configuration page.
Researcher notes
Root cause is unsafe HTML rendering of attacker-controlled configuration key names. Scope, authentication, and UI-triggered execution support CVSS 5.4. The provided sources identify version 0.8.5 and commit 8436e2821988637ed7bfc5562544d089e6b29478 as the fix reference.
Mitigation direction
- Upgrade quark-auto-save to version 0.8.5.
- Check vendor release notes and patch guidance before deployment.
- Restrict System Configuration access to trusted administrators.
- Review persisted configuration keys for unexpected HTML or script-like content.
- Reset sessions for users who viewed suspicious configuration pages.
Validation and detection
- Confirm the deployed quark-auto-save version is 0.8.5 or newer.
- Review the patch for removal of unsafe v-html rendering.
- Inspect stored push_config key names for suspicious markup.
- Check access logs for unexpected POST /update activity.
- Verify only authorized users can access System Configuration.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
