Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated WordPress session with the Editor role (or a role of equivalent or higher standing granted by the plugin's incorrect assignment logic). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 7.2 score with vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H signals that while the attack is network-accessible and requires no user interaction, exploitation is gated behind a high-privilege account (PR:H). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who holds a WordPress Editor account - obtained via credential theft, account compromise, or legitimate provisioning on a multi-author site - sends a crafted request to a FluentCRM Pro endpoint that fails to enforce role boundaries. The plugin incorrectly grants the Editor elevated privileges, such as Administrator, enabling the attacker to install malicious plugins, create new admin accounts, exfiltrate the site database, or fully deface or take over the WordPress installation. …
Remediation Update FluentCRM Pro to a version beyond 3.1.12 as soon as one is confirmed available from WP Manage Ninja. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI
