Security readout for executives and security teams
Plain-English summary
CVE-2026-27383 affects the RadiusTheme Metro WordPress theme through version 2.13. It is a local file inclusion issue that could let an unauthenticated attacker cause the site to include unintended local PHP files. The published CVSS score is 8.1, high severity. No provided source states active exploitation.
Executive priority
Treat this as a high-priority WordPress exposure review, especially for public-facing sites using Metro. The issue is high impact and unauthenticated, but available sources do not show confirmed exploitation. Prioritize identifying whether the theme exists in your environment, then follow vendor or Patchstack remediation guidance.
Technical view
The CVE describes improper control of a filename used in a PHP include/require statement, categorized as CWE-98. Scope is Metro WordPress theme versions up to and including 2.13. The CVSS vector is AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating network reachability, no required authentication, high attack complexity, and potential full confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress sites with the RadiusTheme Metro theme installed at version 2.13 or earlier. Sites not using this theme are not indicated as affected. The source bundle has inconsistent affected-version metadata, so confirm against vendor or Patchstack records.
Exploitation context
The CVE is not listed as CISA KEV in the provided data, and no cited source claims active exploitation. Exploitation is rated high complexity, but requires no authentication or user interaction according to CVSS. Local file inclusion can become serious depending on reachable files and server configuration.
Researcher notes
Evidence comes from the CVE record and Patchstack reference. The description states Metro through 2.13 is affected, while the structured affected data is sparse and internally inconsistent. No patch version, proof-of-concept, or exploitation-in-the-wild claim is included in the provided sources.
Mitigation direction
- Inventory WordPress sites for the RadiusTheme Metro theme.
- Identify installed Metro versions and flag versions 2.13 or earlier.
- Check RadiusTheme and Patchstack guidance for an official fix or workaround.
- Update, replace, or disable the theme if vendor guidance indicates risk.
- Prioritize backups and recovery readiness for exposed WordPress sites.
Validation and detection
- Confirm whether Metro is installed, active, or present on each WordPress site.
- Record the exact Metro theme version from trusted administrative inventory.
- Compare findings against the CVE and Patchstack affected range.
- Review web logs for suspicious file-include style requests, without assuming compromise.
- Document remediation status and recheck after any theme update or removal.
