Security readout for executives and security teams
Plain-English summary
CVE-2026-25346 is a cross-site scripting vulnerability in the WordPress FAQ Builder AYS plugin, affecting versions up to and including 1.8.2. An attacker may be able to cause malicious script to run in a user’s browser if interaction occurs. For businesses, the concern is compromised website trust, user session exposure, and possible content manipulation.
Executive priority
Treat this as a high-priority WordPress plugin issue where the plugin is installed on public or business-critical sites. Prioritize inventory and version checks first. If affected versions are present and no patch is available, consider disabling the plugin until vendor guidance is clear.
Technical view
The issue is CWE-79 improper neutralization during web page generation in Ays Pro FAQ Builder AYS faq-builder-ays. The CVSS 3.1 score is 7.1 with network access, low attack complexity, no privileges required, and user interaction required. Scope is changed, with low confidentiality, integrity, and availability impact. Sources do not provide exploit details or a confirmed fixed version.
Likely exposure
Exposure is most likely on WordPress sites with the FAQ Builder AYS plugin installed at version 1.8.2 or earlier. The provided CVE data lists the default status as unaffected but specifically identifies versions through 1.8.2 as affected, so asset-level plugin version validation is important.
Exploitation context
The CVSS vector indicates remote exploitation is possible, does not require attacker privileges, but does require user interaction. The source bundle does not show CISA KEV listing or other evidence of active exploitation. No public exploit status is established from the provided sources.
Researcher notes
Evidence is limited to the CVE record and Patchstack reference. The description mentions XSS and incorrectly configured access control security levels, but no vulnerable parameter, exploit workflow, patch commit, or fixed version is provided in the source bundle. Avoid assuming exploitation in the wild without additional sourced confirmation.
Mitigation direction
- Inventory WordPress sites for the FAQ Builder AYS plugin.
- Identify installations running version 1.8.2 or earlier.
- Check vendor and Patchstack guidance for a fixed release or official mitigation.
- Update the plugin if a patched version is available from trusted sources.
- Temporarily disable the plugin where risk is unacceptable and no fix is available.
Validation and detection
- Confirm installed plugin name and version on each WordPress site.
- Review FAQ Builder AYS pages and admin areas for unexpected script content.
- Check web application logs for suspicious requests targeting plugin FAQ functionality.
- Verify any update or disablement through WordPress plugin inventory.
- Monitor the CVE and Patchstack entry for fixed-version details.
