Security readout for executives and security teams
Plain-English summary
CVE-2026-28097 affects the WordPress Artrium theme from ThemeREX through version 1.0.14. It is a local file inclusion issue that may let an unauthenticated remote attacker access or influence files handled by the site. The published CVSS score is high at 8.1.
Executive priority
Treat this as a near-term WordPress exposure review. It is high severity and unauthenticated, but public evidence does not show active exploitation. Prioritize internet-facing WordPress sites using Artrium, especially business-critical or customer-facing sites.
Technical view
The issue is classified as CWE-98: improper control of a filename used in a PHP include/require statement. Public records describe PHP Local File Inclusion in Artrium <= 1.0.14. CVSS indicates network attack vector, no privileges, no user interaction, high complexity, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is likely limited to WordPress sites using the ThemeREX Artrium theme at version 1.0.14 or earlier. The sources do not identify affected hosting configurations, specific vulnerable endpoints, or whether inactive installations are exploitable.
Exploitation context
The CVE record rates exploitation as remote and unauthenticated but high complexity. CISA KEV status is false in the provided data, and no cited source states active exploitation. Public details are limited to the vulnerability class, affected theme, version range, and severity.
Researcher notes
Evidence is sparse. The CVE description and Patchstack entry identify Artrium <= 1.0.14 and LFI, but no patch version, endpoint, proof of concept, or exploitation-in-the-wild claim is cited. The structured affected metadata appears limited, so validate against vendor advisory data.
Mitigation direction
- Inventory WordPress sites for the Artrium theme and record installed versions.
- If Artrium is present at <= 1.0.14, check ThemeREX and Patchstack guidance.
- Apply a vendor-provided fixed version if one is available.
- Remove or replace the theme where it is not required.
- Prioritize backups and least-privilege file permissions while awaiting vendor guidance.
Validation and detection
- Confirm the active WordPress theme and Artrium version on each site.
- Check whether the site matches the <= 1.0.14 affected range.
- Review web logs for unusual requests targeting theme files or include paths.
- Verify remediation against vendor or Patchstack advisory details.
- Document any sites where no fixed version is available.
