Security readout for executives and security teams
Plain-English summary
CVE-2026-22405 affects the WordPress Overton theme from Mikado-Themes through version 1.3. It can allow local file inclusion, which may expose or affect server-side files. The CVSS score is 8.1 high. Public sources do not state active exploitation or name a specific patched version.
Executive priority
Treat as high priority for any public WordPress site using Overton <= 1.3. Prioritize inventory and containment first because sources do not identify a patch. Do not assume active exploitation without further evidence.
Technical view
The issue is CWE-98: improper control of a filename used in PHP include/require logic. The CVSS vector is AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating unauthenticated network reachability but high attack complexity. Sources identify Overton theme versions up to and including 1.3 as affected.
Likely exposure
Exposure is limited to WordPress sites using the Mikado-Themes Overton theme at version 1.3 or earlier. Sites not using this theme are not indicated as affected by the provided sources.
Exploitation context
The CVE is not listed as KEV in the provided bundle, and the cited sources do not report active exploitation. The high CVSS impact suggests serious consequences if exploited, but attack complexity is rated high.
Researcher notes
The public record is sparse. Patchstack and CVE data identify the vulnerability class, affected theme, version range, and CVSS. They do not provide exploit details, patch status, or confirmed exploitation. Validate against live asset inventory before escalation.
Mitigation direction
- Inventory WordPress sites for the Overton theme and version number.
- If Overton <= 1.3 is present, review vendor and Patchstack guidance immediately.
- If no safe update is available, consider disabling or replacing the theme.
- Limit public exposure of affected WordPress sites where business operations allow.
- Monitor vendor advisories for a patched release or official workaround.
Validation and detection
- Confirm whether the Overton theme is installed on each WordPress site.
- Record installed Overton versions and flag versions 1.3 or earlier.
- Check security monitoring for unusual file access or PHP include-related errors.
- Verify whether any vendor-provided update or workaround has been applied.
- Document compensating controls if the theme cannot be removed promptly.

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')
Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
