Security readout for executives and security teams
Plain-English summary
CVE-2026-27988 affects the WordPress Equadio theme by ThemeREX through version 1.1.3. It may let an unauthenticated attacker force the site to include local files, risking data exposure, code execution conditions, or site disruption. The CVSS score is high at 8.1, but attack complexity is rated high.
Executive priority
Prioritize identification and remediation for any public WordPress site using Equadio. The business risk is high because successful exploitation could compromise sensitive data, site integrity, or availability. Urgency is lower than confirmed exploited KEV issues, but public-facing affected sites should be handled promptly.
Technical view
The issue is CWE-98: improper control of filename in a PHP include/require statement, described as PHP Local File Inclusion in Equadio <= 1.1.3. The CVSS vector is AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating remote unauthenticated attack surface with high confidentiality, integrity, and availability impact if exploited.
Likely exposure
Exposure is limited to WordPress sites using the ThemeREX Equadio theme, especially versions up to and including 1.1.3. The provided data does not identify a fixed version. Sites not using Equadio are not indicated as affected by these sources.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The vulnerability is remotely reachable and unauthenticated per CVSS, but exploitation complexity is high. No exploit maturity details are provided in the sources.
Researcher notes
The provided metadata has some inconsistency: the description says Equadio through <= 1.1.3, while the affected version entry lists version 0 with defaultStatus unaffected. Use the narrative description and Patchstack reference as primary scoping evidence, and verify against vendor advisories before enforcement actions.
Mitigation direction
- Inventory WordPress sites for the ThemeREX Equadio theme and installed version.
- If Equadio is present at <= 1.1.3, treat the site as potentially exposed.
- Check ThemeREX, Patchstack, and WordPress admin channels for an official fixed version or guidance.
- If no fix is available, consider disabling or replacing the theme after business impact review.
- Restrict administrative access and monitor web logs for suspicious file-include related behavior.
Validation and detection
- Confirm whether the Equadio theme is installed on each WordPress instance.
- Record the installed Equadio version and compare it to <= 1.1.3.
- Review vendor or Patchstack advisory pages for updated remediation status.
- Check whether the site has compensating controls such as WAF rules or hardened PHP configuration.
- Look for unusual requests or errors referencing theme PHP include behavior.

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.
