Summary
The ShopLentor plugin for WordPress is vulnerable to arbitrary function execution via the woolentoropt/v1/custom-action REST API endpoint in all versions up to, and including, 3.3.7. This is due to the handle_action() method passing user-supplied input directly to call_user_func() without an allowlist of permitted callbacks. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute arbitrary PHP callable functions via the 'callback' parameter.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
