Security readout for executives and security teams
Plain-English summary
CVE-2026-22376 affects the WordPress Parkivia theme through version 1.1.9. It may let an unauthenticated remote attacker include local server files through unsafe PHP file handling. Business urgency is highest for public WordPress sites using this theme, especially where sensitive configuration files are present.
Executive priority
Treat as a near-term remediation item for any public WordPress site using Parkivia <= 1.1.9. The potential impact is high, but current public evidence does not show known active exploitation or a named patch in the provided sources.
Technical view
The issue is described as CWE-98 improper control of filenames in PHP include/require logic, resulting in local file inclusion in AncoraThemes Parkivia <= 1.1.9. CVSS 3.1 is 8.1 high: network exploitable, high complexity, no privileges or user interaction, with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress installations using the Parkivia theme at version 1.1.9 or earlier. Internet-facing sites are the primary concern. The supplied data does not identify specific vulnerable parameters, affected files, or whether inactive installed themes are exploitable.
Exploitation context
The CVE is not listed as CISA KEV in the provided data, and no cited source states active exploitation. Public metadata indicates unauthenticated network reachability but high attack complexity. No exploit code or operational exploitation details are included in the source bundle.
Researcher notes
Source data is sparse. The record labels CWE-98 and references PHP remote file inclusion wording, while the described outcome is local file inclusion. CVSS shows high complexity despite unauthenticated network attack. No vulnerable endpoint, proof-of-concept, patch version, or exploit-in-the-wild evidence is provided.
Mitigation direction
- Inventory WordPress sites for the Parkivia theme and record installed versions.
- Prioritize internet-facing sites running Parkivia version 1.1.9 or earlier.
- Check AncoraThemes and Patchstack for fixed-version or mitigation guidance.
- Update, remove, or replace the theme if no fixed release is available.
- Review site backups and change-control plans before theme replacement.
Validation and detection
- Confirm whether Parkivia is installed and active on each WordPress site.
- Verify the installed theme version from WordPress administration or asset inventory.
- Review web logs for unusual requests targeting theme PHP files.
- Check file integrity and configuration files for unexpected exposure indicators.
- Track CVE, vendor, and Patchstack pages for updated remediation details.

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.
