CVE intelligence and bounded remediation
CVE-2022-4935 — Wclovers Wcfm Marketplace security vulnerability
The WCFM Marketplace plugin for WordPress is vulnerable to unauthorized modification and access of data in versions up to, and including, 3.4.11 due to missing capability checks on various AJAX actions. This makes it possible for authenticated attackers, with minimal permissions such as subscribers, to perform a wide variety of actions such as modifying shipping method details, modifying products, deleting arbitrary posts, and privilege escalation (via the wp_ajax_wcfm_vendor_store_online AJAX action).

Matched remediation archetype
Authorization bypass, IDOR, and cross-tenant access
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
- Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
- Use synthetic fixtures to compare intended access matrices without accessing another user's real data.
Remediate safely
- Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
- Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
- Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
