Security readout for executives and security teams
Plain-English summary
CVE-2026-28094 affects the WordPress RexCoin theme by ThemeREX through version 1.2.6. It can allow an unauthenticated remote attacker to include local files through unsafe PHP file handling. The reported impact is high across confidentiality, integrity, and availability. No provided source confirms active exploitation.
Executive priority
Treat this as a high-priority WordPress exposure for any site using RexCoin. The business risk is strongest for public websites, where compromise could affect data, site integrity, or availability. If RexCoin is not deployed, urgency is low.
Technical view
The issue is classified as CWE-98, improper control of filenames in PHP include/require logic, resulting in local file inclusion. CVSS 3.1 is 8.1 with AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H. The affected product is ThemeREX RexCoin WordPress theme up to and including 1.2.6.
Likely exposure
Exposure is likely limited to WordPress sites using the RexCoin theme version 1.2.6 or earlier. Sites not using this theme are not indicated as affected by the supplied sources.
Exploitation context
The CVSS vector indicates network reachability, no authentication, and no user interaction, but high attack complexity. The CVE is not listed as KEV in the supplied data, and no cited source states active exploitation.
Researcher notes
Public details are limited in the supplied sources. The record identifies an LFI condition in RexCoin through 1.2.6 with high impact and high attack complexity. Do not assume exploit availability or a patch unless confirmed by Patchstack, ThemeREX, or updated CVE data.
Mitigation direction
- Inventory WordPress sites for the ThemeREX RexCoin theme.
- Identify any RexCoin installations at version 1.2.6 or earlier.
- Check ThemeREX and Patchstack guidance for a fixed version or recommended mitigation.
- If no fix is available, consider removing or replacing the theme.
- Prioritize externally reachable WordPress sites using the affected theme.
Validation and detection
- Confirm the active and installed theme names on each WordPress site.
- Record the RexCoin theme version from WordPress inventory or theme metadata.
- Compare discovered versions against the affected range: through 1.2.6.
- Review web logs for unusual requests targeting RexCoin theme paths.
- Monitor the CVE and Patchstack entries for updated remediation details.
