Security readout for executives and security teams
Plain-English summary
CVE-2026-28089 is a high-severity local file inclusion issue in the WordPress Daiquiri theme from ThemeREX, affecting versions through 1.2.4. A remote, unauthenticated attacker may be able to cause the site to include unintended local files. The public sources do not confirm active exploitation or name a fixed version.
Executive priority
Treat as a priority for WordPress asset owners using Daiquiri. The potential impact is high, but urgency depends on whether the theme is deployed and whether vendor remediation is available. Start with inventory and removal or update decisions.
Technical view
The flaw is classified as CWE-98: improper control of filenames used in PHP include/require statements. CVSS 3.1 is 8.1 with network access, no privileges, no user interaction, high attack complexity, and high confidentiality, integrity, and availability impact. The CVE description identifies Daiquiri <= 1.2.4 as affected.
Likely exposure
Exposure is limited to WordPress sites using the ThemeREX Daiquiri theme at version 1.2.4 or earlier. Sites not using this theme are not indicated as affected by the provided sources.
Exploitation context
No provided source states active exploitation, and the CVE is not marked as CISA KEV in the bundle. The CVSS vector indicates exploitation is remotely reachable without authentication, but attack complexity is high.
Researcher notes
Source detail is limited. The CVE references PHP file inclusion behavior and Patchstack’s vulnerability entry, but the bundle does not provide vulnerable parameters, exploit evidence, or a fixed version. Avoid assuming broader ThemeREX product impact.
Mitigation direction
- Inventory WordPress sites for the ThemeREX Daiquiri theme and version.
- Check ThemeREX, WordPress theme marketplace, or Patchstack for vendor remediation guidance.
- Update the theme if a fixed version is available from trusted sources.
- Disable or remove the theme where it is unused or cannot be remediated.
- Apply compensating monitoring until vendor guidance or a fixed version is confirmed.
Validation and detection
- Confirm whether Daiquiri is installed on each WordPress site.
- Record the installed Daiquiri version and compare against <= 1.2.4.
- Review vendor and Patchstack advisories for fixed-version information.
- Check web logs for unusual requests to theme PHP endpoints or include-like parameters.
- Validate remediation by confirming the vulnerable theme version is no longer present.
