Security readout for executives and security teams
Plain-English summary
CVE-2026-22371 affects the Gustavo WordPress theme, reported as vulnerable through version 1.2.2. It may let an unauthenticated internet user cause the site to include local server files. The reported impact is high for confidentiality, integrity, and availability, but attack complexity is high and no active exploitation is indicated in the provided sources.
Executive priority
Treat as a high-priority WordPress exposure if Gustavo is deployed. Business urgency is greatest for public websites using affected versions. If the theme is not present, no direct action is needed beyond documenting non-exposure.
Technical view
The issue is an improper filename control flaw in a PHP include/require path, classified as CWE-98. The CVSS v3.1 score is 8.1: network reachable, unauthenticated, no user interaction, high attack complexity, and high CIA impact. Sources describe local file inclusion in AncoraThemes Gustavo <=1.2.2.
Likely exposure
Exposure is limited to WordPress installations using the Gustavo theme at versions up to 1.2.2, especially internet-facing sites. The provided affected-version data is somewhat inconsistent, so teams should verify theme presence and version directly.
Exploitation context
No CISA KEV listing or cited source in the bundle indicates active exploitation. The vulnerability is remotely reachable and unauthenticated, but CVSS marks attack complexity as high. Public detail is limited to vulnerability database descriptions, not operational exploit evidence.
Researcher notes
The CVE description says Gustavo through <=1.2.2 is affected, while the structured affected entry lists version data unclearly. Do not assume broader product impact. No patch details, exploit publication, or exploitation-in-the-wild evidence are provided in the supplied sources.
Mitigation direction
- Inventory WordPress sites for the Gustavo theme and installed version.
- Check AncoraThemes and Patchstack guidance for an official fix or workaround.
- Update the theme if a vendor-supported fixed version is available.
- Disable or remove the theme where it is not required.
- Prioritize controls and monitoring for internet-facing WordPress sites using Gustavo.
Validation and detection
- Confirm whether Gustavo is installed on each WordPress site.
- Record the installed Gustavo version and compare against <=1.2.2.
- Review vendor and Patchstack pages for updated remediation status.
- Check web and WordPress logs for unusual file access errors or include-related anomalies.
- Document whether each site is remediated, removed, or awaiting vendor guidance.

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.
