CVE-2023-0713: Wicked Folders <= 2.18.16 - Missing Authorization on ajax_add_folder

The Wicked Folders plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the ajax_add_folder function in versions up to, and including, 2.18.16. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to invoke this function and perform actions intended for administrators such as modifying the folder structure maintained by the plugin.

Security readout for executives and security teams

Plain-English summary

CVE-2023-0713 lets a logged-in low-privilege WordPress user change Wicked Folders folder structure through an AJAX function intended for administrators. The impact is limited to plugin-managed organization data, but it can disrupt editorial workflows and content management order.

Executive priority

Treat as a moderate-priority hygiene fix. It is not a site takeover issue from the supplied evidence, but it can affect content operations wherever untrusted authenticated users exist.

Technical view

Wicked Folders versions up to and including 2.18.16 miss an authorization capability check in ajax_add_folder. An authenticated attacker with subscriber-level access or higher can invoke the function and modify plugin folder structure. The issue is CWE-862 with CVSS 3.1 score 5.4.

Likely exposure

Exposure is limited to WordPress sites running Wicked Folders <= 2.18.16 that allow untrusted or weakly controlled authenticated accounts, including subscribers. Public, membership, customer portal, or contributor-heavy sites have higher practical exposure.

Exploitation context

The supplied bundle does not identify active exploitation, and KEV is false. Exploitation requires authenticated WordPress access, so risk depends heavily on whether low-privilege accounts exist and how easily they can be created or compromised.

Researcher notes

Focus validation on the missing capability check around ajax_add_folder in the 2.18.16 plugin code and compare it with the referenced WordPress Trac changeset. Avoid assuming broader content edit, privilege escalation, or unauthenticated reach without additional evidence.

Mitigation direction

  • Inventory WordPress sites using Wicked Folders and record installed plugin versions.
  • Update Wicked Folders beyond 2.18.16 where available, following vendor or Wordfence guidance.
  • Restrict or remove unnecessary subscriber and contributor accounts on affected sites.
  • Monitor plugin folder changes for unauthorized or unexplained modifications.
  • Check vendor guidance if no safe update path is available.

Validation and detection

  • Confirm whether Wicked Folders is installed and enabled on each WordPress site.
  • Verify the installed version is not 2.18.16 or earlier.
  • Review WordPress users with subscriber-level or higher access for unnecessary accounts.
  • Check administrative logs or plugin data for unexpected folder structure changes.
  • Confirm remediation in a staging environment before production rollout.

Missing Authorization

Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
