The WP Fusion (Pro) plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.47.13. This is due to insufficient authorization checks on the role parameter in the ThriveCart Auto Login handler's thrivecart() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, and who possess the access_key, to create a new user account with administrator privileges and gain full control over the WordPress site. The required access_key is intentionally shared with ThriveCart customers as part of the plugin's documented setup process, making it accessible to attackers who have made a purchase. The vulnerability is only exploitable when the ThriveCart Auto Login option is enabled.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Two explicit preconditions must both be satisfied: (1) the ThriveCart Auto Login option must be deliberately enabled within the WP Fusion plugin settings - this is a non-default integration feature, not active in standard installations without ThriveCart configuration; and (2) the attacker must possess the site's WP Fusion access_key, which per the CVE description is intentionally shared with all ThriveCart customers as part of the plugin's documented setup process, meaning any historical purchaser from the operator's ThriveCart account may hold it. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H, score 7.5) accurately captures the two hard prerequisites that justify AC:H: the ThriveCart Auto Login feature must be explicitly enabled by the site operator, and the attacker must hold the plugin's access_key. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
