Security readout for executives and security teams
Plain-English summary
CVE-2026-28093 affects the WordPress Ozisti theme from ThemeREX through version 1.1.10. An unauthenticated remote attacker may be able to make the site include local PHP files, risking data exposure, site modification, or disruption. Public sources rate it high severity, but exploitation requires high attack complexity.
Executive priority
Treat as a high-priority WordPress exposure review for sites using Ozisti. Prioritize internet-facing, business-critical, or high-traffic WordPress properties. If the theme is present and no fix is confirmed, reduce exposure by disabling or replacing it where practical.
Technical view
The issue is classified as CWE-98: improper control of filenames in PHP include/require statements. The CVSS 3.1 score is 8.1 with AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H. Sources describe PHP Local File Inclusion in Ozisti theme versions up to and including 1.1.10.
Likely exposure
Exposure is likely limited to WordPress sites using the ThemeREX Ozisti theme at version 1.1.10 or earlier. Sites not using this theme are not indicated as affected by the provided sources.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. The CVSS vector indicates network reachability, no required authentication, and no user interaction, but high attack complexity.
Researcher notes
Evidence is limited to the CVE record and Patchstack entry in the source bundle. The bundle names Ozisti through 1.1.10 as affected, but does not provide a patched version, proof of exploitation, or detailed vulnerable parameter information.
Mitigation direction
- Inventory WordPress sites for the Ozisti theme and record installed versions.
- If Ozisti is version 1.1.10 or earlier, check ThemeREX or Patchstack guidance.
- Apply any vendor-provided patched theme release when available.
- Disable or replace the theme if it is unused or cannot be safely remediated.
- Review WordPress and hosting file permissions as part of general hardening.
Validation and detection
- Confirm whether Ozisti is installed on each WordPress site.
- Verify the installed Ozisti version is above 1.1.10 or otherwise vendor-cleared.
- Check vendor and Patchstack pages for updated remediation information.
- Review web logs for suspicious requests targeting Ozisti theme paths.
- Confirm backups and recovery procedures before making theme changes.

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.
