Security readout for executives and security teams
Plain-English summary
CVE-2026-22457 is a high-severity local file inclusion issue in the WordPress Wanderland theme by Mikado-Themes, affecting versions through 1.5. A remote unauthenticated attacker may be able to cause sensitive file access or broader compromise, but exploitation complexity is rated high. No active exploitation is indicated in the provided sources.
Executive priority
Treat this as a near-term remediation item for any WordPress site using Wanderland <=1.5, especially internet-facing sites. Prioritize discovery first because exposure depends on theme presence and version. Urgency is high, but available sources do not show confirmed exploitation.
Technical view
The issue is described as improper control of a filename used in PHP include/require logic, mapped to CWE-98. The CVSS 3.1 score is 8.1 with network attack vector, no privileges, no user interaction, high complexity, and high confidentiality, integrity, and availability impact. Sources identify Wanderland theme <=1.5 as affected.
Likely exposure
Exposure is most likely on public WordPress sites with the Mikado-Themes Wanderland theme installed at version 1.5 or earlier. The source bundle does not clarify whether inactive installed themes are exploitable, so vulnerability managers should inventory both active and installed copies.
Exploitation context
The CVSS vector indicates remote unauthenticated exploitation with no user interaction, but high attack complexity. The CVE is not listed as KEV in the provided data, and no cited source states active exploitation. Public details in the bundle are limited.
Researcher notes
Evidence is sparse beyond the CVE metadata and Patchstack entry. The affected range is stated as through <=1.5, while structured affected data in the bundle is inconsistent. Do not assume a patch version from the provided sources. Validate against vendor/Patchstack updates before closure.
Mitigation direction
- Check vendor and Patchstack guidance for an official fixed version or mitigation.
- Upgrade Wanderland if a fixed release is available from the vendor.
- Remove the theme if it is unused or no longer required.
- Restrict administrative and file-level access to the WordPress host.
- Ensure recent, tested backups exist before making changes.
Validation and detection
- Inventory WordPress sites for the Wanderland theme.
- Confirm installed Wanderland versions, including inactive copies.
- Flag any Wanderland installation at version 1.5 or earlier.
- Review vendor or Patchstack advisories for updated remediation status.
- Monitor logs for unusual file access patterns, without assuming compromise.
