Security readout for executives and security teams
Plain-English summary
CVE-2026-31919 is a broken access control issue in the WordPress Advanced Coupons for WooCommerce Coupons plugin through version 4.7.1. A logged-in user may access data they should not be allowed to see. The available scoring rates this as medium severity, focused on limited confidentiality impact rather than site takeover or service disruption.
Executive priority
Prioritize in the normal vulnerability remediation cycle, with faster handling for public WooCommerce sites that allow customer or subscriber logins. Current evidence supports moderate business urgency, not emergency response, because impact is limited and no active exploitation is reported in the provided sources.
Technical view
The CVE describes CWE-862 Missing Authorization in advanced-coupons-for-woocommerce-free through 4.7.1. CVSS 3.1 is 4.3: network reachable, low complexity, low privileges required, no user interaction, unchanged scope, low confidentiality impact, no integrity or availability impact. Public sources do not name a fixed version or detailed vulnerable endpoint.
Likely exposure
Exposure is likely limited to WordPress/WooCommerce sites running Advanced Coupons for WooCommerce Coupons version 4.7.1 or earlier. Because exploitation requires low privileges, sites with customer accounts, subscriber registration, or many low-trust users should treat this as more relevant than closed administrative-only sites.
Exploitation context
The source bundle does not report active exploitation, and the CVE is not marked as CISA KEV. The issue appears remotely reachable by an authenticated user, but public sources provided do not include exploit details, proof-of-concept status, or evidence of weaponization.
Researcher notes
Key missing details are the affected function, endpoint, required role, and fixed version. Validation should focus on asset inventory and version exposure rather than exploit reproduction. Treat Patchstack and vendor updates as authoritative for remediation specifics once they publish more detail.
Mitigation direction
- Inventory WordPress sites using Advanced Coupons for WooCommerce Coupons.
- Identify installations running version 4.7.1 or earlier.
- Check vendor and Patchstack guidance for a fixed release or workaround.
- Update the plugin when an official fixed version is available.
- Limit untrusted user registration where business requirements allow.
- Review plugin access permissions for unnecessary low-privilege access.
Validation and detection
- Confirm the installed plugin package is advanced-coupons-for-woocommerce-free.
- Record plugin version across production and staging sites.
- Compare versions against the affected range: through 4.7.1.
- Review WordPress user roles with access to coupon-related features.
- Check web and application logs for unusual authenticated access patterns.
- Track CVE, vendor, and Patchstack pages for remediation updates.
