Security readout for executives and security teams
Plain-English summary
CVE-2026-27342 affects the TopFit Fitness and Gym WordPress theme through version 1.9. It may let an unauthenticated remote attacker include local files through vulnerable PHP include logic, potentially exposing sensitive data or enabling broader compromise. No source provided confirms active exploitation.
Executive priority
Treat as a high-priority WordPress exposure review, especially for public sites. Focus first on confirming whether the TopFit theme is present. If present and still required, seek vendor guidance promptly because the source bundle does not name a fixed version.
Technical view
The issue is CWE-98: improper control of filenames in PHP include/require statements, described as local file inclusion in Mikado-Themes TopFit. CVSS 3.1 is 8.1 high: network reachable, no privileges or user interaction, high attack complexity, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is most likely on internet-facing WordPress sites using the TopFit theme at version 1.9 or earlier. The provided data does not identify affected configurations beyond the theme and version range.
Exploitation context
The CVSS vector indicates unauthenticated network exploitation is possible but high complexity. The CVE record and source bundle do not state public exploit availability or active exploitation, and CISA KEV status is false.
Researcher notes
The record describes LFI under CWE-98, but the provided sources do not include technical root cause, vulnerable parameter, proof of concept, or fixed release details. Avoid assuming exploitability details beyond the CVSS and description.
Mitigation direction
- Identify WordPress sites using the TopFit theme.
- If TopFit is unused, remove or replace it.
- If TopFit is required, check vendor and Patchstack guidance for an update or workaround.
- Prioritize compensating controls for public sites until vendor remediation is confirmed.
- Back up sites before theme changes.
Validation and detection
- Confirm installed TopFit theme version on each WordPress site.
- Flag versions 1.9 and earlier as potentially affected.
- Review vendor, CVE, and Patchstack pages for remediation status updates.
- Check web and application logs for unusual file access patterns.
- Document sites where the theme cannot be immediately removed.

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.
