PR:L captures mandatory contributor auth; UI:N is defensible because auto_open bypasses victim interaction; S:C reflects XSS scope crossing to victims' browsers; C:L/I:L typical for stored XSS, A:N as no availability impact.

2DescriptionCVE.org
The Social Chat - Click To Chat App Button plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'consent_message' JSON Attribute in .qlwapp data-box in all versions up to, and including, 8.6.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit requires no user interaction beyond page load, as setting auto_open and consent_enabled to 'yes' in the injected data-box JSON causes the consent box - and the embedded script - to execute immediately on page load.

When auto_open and consent_enabled are both set to 'yes' in the injected configuration, the malicious script fires immediately on page load with no additional victim interaction required, enabling session-cookie theft, credential harvesting, or malicious redirects against any visitor who loads the affected page. …
