Security readout for executives and security teams
Plain-English summary
CVE-2026-1883 affects the Wicked Folders WordPress plugin through version 4.1.0. A logged-in user with Contributor or higher privileges can delete folders created by other users. This is not a public unauthenticated takeover issue, but it can disrupt site content organization and workflows where lower-privileged accounts exist.
Executive priority
Treat as a routine but timely WordPress plugin remediation. Prioritize sites with many contributors or shared editorial workflows. The main risk is unauthorized deletion of organizational folders, not full site compromise based on current sources.
Technical view
The plugin has an insecure direct object reference in delete_folders() caused by missing validation on a user-controlled key. Authenticated Contributor+ users can target arbitrary folders owned by other users. CVSS 3.1 is 4.3: network-accessible, low complexity, low privileges, no user interaction, integrity impact only.
Likely exposure
WordPress sites running Wicked Folders – Folder Organizer for Pages, Posts, and Custom Post Types version 4.1.0 or earlier are potentially exposed, especially where Contributor, Author, Editor, or Administrator accounts are broadly assigned.
Exploitation context
The provided sources do not indicate active exploitation, and this CVE is not listed as CISA KEV. Exploitation requires an authenticated account with Contributor-level access or higher, limiting exposure compared with unauthenticated plugin vulnerabilities.
Researcher notes
This is CWE-639 authorization bypass/IDOR in delete_folders(). Evidence points to missing object ownership or authorization validation around a user-controlled key. Public sources provide impact and a WordPress Trac changeset, but no confirmed exploitation or detailed fixed version in the supplied bundle.
Mitigation direction
- Identify sites using Wicked Folders and record installed versions.
- Update the plugin according to WordPress or vendor guidance.
- If no safe update is available, restrict Contributor+ access to trusted users.
- Review and reduce unnecessary WordPress accounts and roles.
- Back up site data before applying plugin changes.
Validation and detection
- Check whether Wicked Folders is installed on each WordPress site.
- Confirm installed versions are not 4.1.0 or earlier.
- Review plugin changelog or WordPress Trac for the referenced fix.
- Audit recent folder deletion activity by non-admin users.
- Verify Contributor users cannot delete folders owned by others after remediation.
