Security readout for executives and security teams
Plain-English summary
CVE-2026-28061 affects the WordPress Tiger Claw theme from ThemeREX, reportedly through version 1.1.14. It is a high-severity local file inclusion issue that could let an unauthenticated attacker make the site include unintended server files. That can expose sensitive data and may affect site integrity or availability.
Executive priority
Prioritize review of public WordPress sites using Tiger Claw. This is high severity and unauthenticated, but there is no provided evidence of active exploitation. Business urgency depends on whether the theme is deployed and whether an official update or workaround is available.
Technical view
The CVE describes improper control of a filename used in a PHP include/require statement, classified as CWE-98. The listed CVSS 3.1 score is 8.1, with network access, no privileges, no user interaction, high attack complexity, and high confidentiality, integrity, and availability impact. The affected range is stated as Tiger Claw through 1.1.14.
Likely exposure
Exposure is likely limited to WordPress installations using the ThemeREX Tiger Claw theme at version 1.1.14 or earlier. The source data does not identify other affected ThemeREX products. The affected metadata contains some inconsistency, so confirm theme name and version directly in WordPress or asset inventory.
Exploitation context
The bundle does not show CISA KEV listing or cited evidence of active exploitation. The vulnerability is remotely reachable and unauthenticated per the CVSS vector, but marked high attack complexity. Treat internet-facing WordPress sites using this theme as the main concern.
Researcher notes
Use caution with the affected-version data: the narrative says through 1.1.14, while the structured affected entry is sparse. Do not assume exploitability beyond Tiger Claw without additional evidence. The available sources do not provide exploit details, patch version, or confirmed exploitation status.
Mitigation direction
- Check ThemeREX and Patchstack guidance for a fixed version or official mitigation.
- Inventory WordPress sites for the Tiger Claw theme and version.
- Prioritize internet-facing sites running Tiger Claw 1.1.14 or earlier.
- If no safe update exists, consider disabling or replacing the theme.
- Back up the site before applying theme changes or updates.
Validation and detection
- Confirm whether the Tiger Claw theme is installed on each WordPress site.
- Record the installed theme version and compare it to 1.1.14 or earlier.
- Check web server and WordPress logs for unusual file access errors or include-related events.
- Verify whether vendor or Patchstack guidance identifies a patched release.
- Document any sites where version or theme provenance cannot be confirmed.
