WPBot exposes visitor contact details without authentication
WPBot from 8.4.9 through versions before 8.6.0 lists stored chat sessions through an AJAX action with no capability or nonce check. An unauthenticated caller can request a broad date range and retrieve every chat visitor's name, email address, and phone number. The authoritative export does not identify the action or date parameters.

- Sep 12, 2026
This CVE was published Sep 12, 2026 and is one of 19 known issues for this plugin.
Update, patch or deactivate.
Update WPBot to 8.6.0 or later. The authoritative affected range ends before 8.6.0. The application-level fix must require an appropriate privacy or chat-management capability, verify a nonce, constrain date ranges, and return only records the caller is authorized to view.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
The WPBot WordPress plugin before 8.6.0 does not perform any capability or nonce check on the AJAX action that lists stored chat sessions, allowing unauthenticated attackers to retrieve the name, email address and phone number of every chat visitor by requesting a wide date range.
