Security readout for executives and security teams
Plain-English summary
CVE-2026-28054 affects the ThemeREX Legal Stone WordPress theme through version 1.2.11. It can let an unauthenticated remote attacker cause the site to include local files improperly. The rated impact is high because successful exploitation could affect confidentiality, integrity, and availability.
Executive priority
Treat this as a high-priority website exposure review. Focus first on public WordPress sites using Legal Stone. If affected, follow vendor or Patchstack remediation guidance and consider temporary removal if the theme is not business-critical.
Technical view
The issue is CWE-98: improper control of filenames used in PHP include/require statements, resulting in local file inclusion. The CVSS 3.1 score is 8.1 with network attack vector, no privileges, no user interaction, and high attack complexity. Sources identify Legal Stone versions through 1.2.11 as affected.
Likely exposure
Exposure is limited to WordPress sites using the ThemeREX Legal Stone theme at version 1.2.11 or earlier. It is not described as a WordPress core issue. Public-facing sites using this theme should be prioritized for inventory and review.
Exploitation context
The CVE record rates exploitation as remotely reachable without authentication or user interaction, but with high attack complexity. The source bundle does not show CISA KEV listing or confirmed active exploitation. No public exploit status is established from the provided sources.
Researcher notes
There is a source inconsistency: the description states affected versions through 1.2.11, while the structured affected entry is sparse. No patch version is included in the provided bundle. Avoid assuming exploit availability or a specific fixed release without vendor confirmation.
Mitigation direction
- Inventory WordPress sites for the Legal Stone theme and its installed version.
- If version is 1.2.11 or earlier, check ThemeREX and Patchstack guidance immediately.
- Apply any vendor-provided update or virtual patch when available.
- Disable or remove the theme where it is not required.
- Increase monitoring for suspicious file inclusion or path-related requests.
Validation and detection
- Confirm whether the Legal Stone theme is installed on each WordPress site.
- Record the exact theme version from WordPress administration or asset inventory.
- Compare installed versions against affected versions through 1.2.11.
- Review vendor and Patchstack pages for fixed-version or mitigation updates.
- Check web logs for unusual file access attempts without probing the vulnerability.

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.
