Security readout for executives and security teams
Plain-English summary
CVE-2026-28015 affects the ThemeREX ShiftCV WordPress theme through version 3.0.14. A flaw in how PHP files are included may let an unauthenticated attacker include local files. For exposed WordPress sites using this theme, the potential business impact includes data exposure, site compromise, or disruption.
Executive priority
Prioritize internet-facing WordPress sites using ShiftCV. The vulnerability is high severity and unauthenticated, but there is no cited active exploitation in the provided sources. Fast inventory and remediation planning are warranted, especially for public marketing or personal-profile sites using this theme.
Technical view
The CVE describes CWE-98: improper control of a filename in a PHP include/require statement, resulting in PHP Local File Inclusion in ShiftCV. It is rated CVSS 8.1 high: network-accessible, unauthenticated, no user interaction, high complexity, with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress sites running the ThemeREX ShiftCV theme at version 3.0.14 or earlier. The provided CPE/version metadata is sparse and partly inconsistent, so validation should use installed theme name and version, not CPE matching alone.
Exploitation context
No CISA KEV listing is provided, and the source bundle does not cite active exploitation. The CVSS vector indicates remote unauthenticated exploitation is possible, but attack complexity is high. Treat internet-facing WordPress sites using this theme as higher priority.
Researcher notes
Evidence is limited to the CVE record and Patchstack reference. The description says ShiftCV through 3.0.14 is affected, while the affected version metadata lists “0,” so version validation may require manual confirmation. The CVE text references CWE-98 and PHP Local File Inclusion, despite the CWE title mentioning remote inclusion.
Mitigation direction
- Inventory WordPress sites for the ThemeREX ShiftCV theme and installed version.
- Check ThemeREX and Patchstack guidance for a fixed version or vendor remediation.
- Update the theme if a vendor-supported fixed release is available.
- If no fix is available, replace or disable ShiftCV where feasible.
- Consider trusted virtual patching or WAF protections if offered by your security provider.
Validation and detection
- Confirm whether ShiftCV is installed on each WordPress site.
- Record the installed ShiftCV version and compare it to <= 3.0.14.
- Review vendor and Patchstack advisories for current remediation status.
- Check web logs for unusual requests targeting theme paths or PHP include behavior.
- Verify the theme is updated, removed, or otherwise mitigated after remediation.

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.
