CVE-2024-8289
Published: 04 September 2024
Summary
CVE-2024-8289 is a critical-severity Missing Authorization (CWE-862) vulnerability in Multivendorx Multivendorx. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 6.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The MultiVendorX plugin for WordPress, versions through 4.2.0, is affected by a missing authorization vulnerability (CWE-862) in its REST API implementation. The update_item_permissions_check and create_item_permissions_check functions in class-mvx-rest-vendors-controller.php lack sufficient capability verification, allowing manipulation of vendor-role accounts and related user data.
Unauthenticated attackers can therefore change passwords for any vendor user, provision new vendor accounts, and demote other roles including administrators to vendor status, resulting in privilege escalation, de-escalation, and account takeover with a CVSS 3.1 score of 9.8.
The EPSS score has remained flat at 0.1010 with no material rise after disclosure. Code references in the plugin repository and the associated Wordfence advisory document the affected functions but do not detail specific mitigation steps beyond the need for an update.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring an access control policy ensures authorization checks are defined and applied for critical functions.
Reviews of access controls detect missing authorization checks on critical functions or resources.
Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.
Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.
The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.
Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.
