Meta Box WordPress plugin before 5.13.1 allows any user holding a Contributor-level role (or equivalent low-privilege account) to permanently delete arbitrary media attachments owned by other users, including administrators, due to a missing authorization check on the deletion endpoint. The root cause is CWE-862: the plugin performs the deletion operation without verifying whether the requesting user has ownership or administrative rights over the target attachment. Publicly available exploit code exists (sourced from WPScan), and while EPSS sits at a low 0.17% (6th percentile), the low attack complexity and wide availability of Contributor accounts on multi-author WordPress sites make this a realistic insider or compromised-account threat.
The Meta Box WordPress plugin before 5.9.4 does not prevent users with at least the contributor role from access arbitrary custom fields assigned to other user's posts. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
The Meta Box - WordPress Custom Fields Framework plugin for WordPress is vulnerable to Stored Cross-Site Scripting via custom post meta values displayed through the plugin's shortcode in all versions.
