5DescriptionCVE.org
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.
AnalysisAI
Unauthenticated information disclosure in the WPBot WordPress chatbot plugin before 8.6.0 allows any remote attacker to bulk-harvest the name, email address, and phone number of every visitor stored in the plugin's chat session history. The vulnerable AJAX action responsible for listing chat sessions applies neither a nonce check nor a WordPress capability gate, leaving it fully accessible to unauthenticated HTTP requests. …

Vulnerability AssessmentAI
| Exploitation | No authentication or elevated privilege is required - any remote attacker with HTTP access to the WordPress site can invoke the vulnerable AJAX action. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) accurately captures the zero-authentication, network-accessible nature of the flaw, though the 'Low' confidentiality rating somewhat understates the privacy exposure - bulk harvesting of name, email, and phone for every chat visitor is a material PII breach, not incidental leakage, and carries direct GDPR implications. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade WPBot to version 8.6.0 or later, which introduces proper capability and nonce validation on the chat session listing AJAX action; this is the only confirmed fix per the WPScan advisory (https://wpscan.com/vulnerability/31d65e66-10b1-467a-8b20-ecf4880359e0/). … Detailed patch versions, workarounds, and compensating controls in full report. |
