Security readout for executives and security teams
Plain-English summary
CVE-2026-22397 affects the WordPress Fleur theme by Mikado-Themes through version 2.2.1. It can allow local files on the web server to be included by PHP. If exploitable, this may expose sensitive data or affect site integrity and availability. No provided source confirms active exploitation.
Executive priority
Treat as a high-priority WordPress exposure if your organization uses Fleur. Public websites using affected versions should be identified quickly. Business urgency is lower for environments without this theme, and there is no cited evidence of active exploitation in the provided sources.
Technical view
The CVE describes improper control of a filename used in a PHP include/require statement, classified as CWE-98. The issue is reported as local file inclusion in the Fleur WordPress theme through 2.2.1. CVSS 3.1 is 8.1 high, network-reachable, unauthenticated, no user interaction, high complexity, with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress installations using the Mikado-Themes Fleur theme at version 2.2.1 or earlier. Sites not using Fleur are not indicated as affected by the provided sources. The affected data lists default status as unaffected except for the specified product/version range.
Exploitation context
The CVSS vector indicates remote, unauthenticated exploitation is possible without user interaction, but with high attack complexity. The source bundle does not include exploit code, proof of concept, or confirmation of in-the-wild exploitation. CISA KEV status is false in the provided data.
Researcher notes
Evidence is limited to the CVE record and Patchstack reference. The description labels CWE-98 and mentions PHP remote file inclusion terminology, while also stating local file inclusion. No patch version, exploit availability, or active exploitation is provided in the bundle; verify vendor advisories before final remediation decisions.
Mitigation direction
- Inventory WordPress sites for the Fleur theme and record installed versions.
- If Fleur is unused, remove or disable it after confirming business impact.
- If Fleur is required, check Mikado-Themes and Patchstack for vendor guidance or updates.
- Prioritize hardening and monitoring for public WordPress sites running affected versions.
Validation and detection
- Confirm whether each WordPress site has the Fleur theme installed.
- Verify the Fleur theme version is greater than 2.2.1 or otherwise vendor-cleared.
- Review web and PHP logs for unusual file inclusion or sensitive file access patterns.
- Document remediation status and any compensating controls for affected sites.
