Security readout for executives and security teams
Plain-English summary
CVE-2026-22431 affects the WordPress Wabi-Sabi theme by AncoraThemes through version 1.2. It can allow local file inclusion through unsafe PHP include/require filename handling. A successful attack could expose sensitive files or affect site integrity and availability. No active exploitation is indicated in the provided sources.
Executive priority
Treat as a high-priority WordPress exposure if the Wabi-Sabi theme is deployed. The business risk is greatest for public websites because successful exploitation may compromise sensitive data or site trust. If the theme is not used, business impact is likely none.
Technical view
The CVE describes CWE-98: improper control of filename in PHP include/require logic, resulting in PHP local file inclusion. CVSS is 8.1 High: network reachable, unauthenticated, no user interaction, high attack complexity, and high confidentiality, integrity, and availability impact. Affected scope is Wabi-Sabi theme versions up to and including 1.2.
Likely exposure
Exposure is limited to WordPress sites that have the AncoraThemes Wabi-Sabi theme installed at version 1.2 or earlier. Sites not using this theme are not indicated as affected by the provided sources.
Exploitation context
The vulnerability is remotely reachable and does not require authentication or user interaction, but CVSS marks attack complexity as high. The source bundle does not cite public exploit activity, CISA KEV listing, or confirmed exploitation in the wild.
Researcher notes
The provided data names Wabi-Sabi through 1.2 as affected and maps the flaw to CWE-98. The affected-version metadata also includes an inconsistent versions value of “0,” so validation should rely on the narrative affected range and vendor/Patchstack details. No patch version is named in the provided bundle.
Mitigation direction
- Identify all WordPress sites using the Wabi-Sabi theme.
- Check the installed Wabi-Sabi theme version.
- If unused, disable or remove the theme.
- Check AncoraThemes or Patchstack guidance for an official fix.
- Prioritize remediation for internet-facing WordPress sites.
Validation and detection
- Confirm whether Wabi-Sabi is installed on each WordPress instance.
- Record the installed theme version and compare against <= 1.2.
- Review web logs for unusual requests targeting theme files.
- Verify any vendor-recommended update or mitigation was applied.
- Re-scan WordPress theme inventory after remediation.
