Security readout for executives and security teams
Plain-English summary
CVE-2026-27340 affects the AncoraThemes Apollo WordPress theme for night club/DJ event sites through version 1.3.1. The flaw can let an unauthenticated remote attacker abuse PHP file inclusion behavior. If your business runs this theme, treat it as urgent because confidentiality, integrity, and availability impacts are rated high.
Executive priority
High priority for organizations using this theme on public websites. Confirm exposure quickly, then follow vendor or Patchstack guidance. Do not assume compromise from the CVE alone, but treat unremediated exposed installations as a material website security risk.
Technical view
The CVE describes improper control of a filename used in PHP include/require logic, mapped to CWE-98. The reported outcome is PHP local file inclusion in Apollo theme versions through 1.3.1. CVSS 3.1 is 8.1: network, high complexity, no privileges, no user interaction, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is likely limited to WordPress sites with the AncoraThemes Apollo theme installed at version 1.3.1 or earlier. Public-facing WordPress sites are the primary concern. The provided sources do not identify other products or a fixed version.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The CVSS vector indicates remote unauthenticated exploitation is possible, but attack complexity is high. Public technical details are limited in the provided sources.
Researcher notes
Details are sparse. The CVE text contains CWE-98 wording for PHP remote file inclusion but describes local file inclusion. Do not broaden affected scope beyond Apollo through 1.3.1. No patch version, exploit evidence, or KEV confirmation is present in the supplied sources.
Mitigation direction
- Inventory WordPress sites for the Apollo theme and version.
- Check AncoraThemes and Patchstack guidance for an official update or mitigation.
- Prioritize remediation for public-facing sites running Apollo 1.3.1 or earlier.
- If no fix is available, consider disabling or replacing the theme after business review.
- Back up the site before theme changes or updates.
Validation and detection
- Confirm whether the Apollo theme is installed on each WordPress site.
- Record the installed theme version and compare it to 1.3.1 or earlier.
- Review vendor and Patchstack pages for fixed-version information.
- Review web logs for unusual requests targeting Apollo theme paths.
- Document remediation status for each affected site.
