Security readout for executives and security teams
Plain-English summary
CVE-2026-22439 affects the WordPress Green Planet theme through version 1.1.14. It may let an unauthenticated attacker make the site include unintended local files. The rated impact is high because confidentiality, integrity, and availability could all be affected, but the CVSS vector says exploitation complexity is high.
Executive priority
Treat as a priority for any public WordPress site using Green Planet. The business risk is potentially significant, but urgency depends on whether the theme is installed and internet-facing. No active exploitation is confirmed in the provided sources.
Technical view
The issue is improper control of a filename used in a PHP include/require statement, reported as Local File Inclusion in AncoraThemes Green Planet <=1.1.14. CVSS 3.1 is 8.1: network-accessible, high complexity, no privileges, no user interaction, unchanged scope, with high C/I/A impact. CWE is listed as CWE-98.
Likely exposure
Exposure is limited to WordPress sites using the AncoraThemes Green Planet theme at version 1.1.14 or earlier. The provided sources do not identify a patched version, affected component path, or required configuration.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Public vulnerability database coverage exists via Patchstack. No exploit procedure is included in the provided sources, and exploitation is rated high complexity.
Researcher notes
Evidence is sparse beyond the CVE record and Patchstack entry. The affected range is clear, but no fixed version, vulnerable parameter, proof of exploitation, or exploitability conditions are provided. Avoid assuming remote code execution without additional vendor detail.
Mitigation direction
- Identify WordPress sites using the Green Planet theme.
- Check whether the installed theme version is 1.1.14 or earlier.
- Review AncoraThemes and Patchstack guidance for an official fix or workaround.
- If no fix is available, consider disabling or replacing the theme after business review.
- Prioritize backups and monitoring for affected WordPress sites.
Validation and detection
- Confirm theme name and version from WordPress administration or asset inventory.
- Compare installed versions against the affected range: through 1.1.14.
- Check vendor and Patchstack pages for updated remediation status.
- Review web logs for unusual requests targeting theme PHP include behavior.
- Document affected sites, owners, exposure, and remediation decisions.

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.
