CVE-2026-57324 Overview
CVE-2026-57324 is a broken access control vulnerability affecting the GIFT4U Gift Cards All-in-One for WooCommerce WordPress plugin in versions up to and including 1.0.10. The flaw allows unauthenticated attackers to interact with plugin functionality that should be restricted to authorized users. The vulnerability is classified under CWE-862: Missing Authorization and is exploitable remotely over the network without user interaction.
Critical Impact
Unauthenticated network attackers can bypass access control checks in the GIFT4U plugin to affect integrity and availability of gift card data in WooCommerce environments.
Affected Products
- GIFT4U Gift Cards All-in-One for WooCommerce plugin versions <= 1.0.10
- WordPress sites running the vulnerable plugin
- WooCommerce stores that rely on GIFT4U for gift card issuance and redemption

Technical Details for CVE-2026-57324
Vulnerability Analysis
The GIFT4U plugin fails to enforce authorization on one or more of its endpoints. Attackers can reach protected functionality without authenticating to WordPress. The flaw sits in the plugin's access control layer, not in input validation or memory safety. According to the Patchstack WordPress Vulnerability Report, all plugin versions through 1.0.10 are affected.
Exploitation impacts integrity and availability of gift card records but does not directly expose confidential data based on the published metrics. Attackers can potentially manipulate gift card state, trigger unintended plugin actions, or disrupt normal shop operations. The EPSS probability is 0.242% with a percentile ranking of 15.247, indicating limited observed exploitation activity at disclosure.
Root Cause
The root cause is missing authorization checks [CWE-862] on plugin actions or REST endpoints. The plugin does not verify user capabilities or nonces before executing sensitive operations. As a result, requests from unauthenticated clients reach code paths that assume a privileged context.
Attack Vector
The attack vector is network-based. An attacker sends crafted HTTP requests to the vulnerable plugin endpoints exposed by the target WordPress site. No authentication, privileges, or user interaction are required. Attack complexity is low, meaning any Internet-reachable WooCommerce site running the vulnerable plugin can be targeted with standard HTTP tooling.
No verified public proof-of-concept code was available at the time of writing. Refer to the Patchstack advisory for further technical detail.
Detection Methods for CVE-2026-57324
Indicators of Compromise
- Unexpected creation, modification, or redemption of gift card records without a corresponding authenticated administrator or customer session.
- HTTP requests from unauthenticated sources hitting GIFT4U plugin endpoints under /wp-admin/admin-ajax.php or /wp-json/ routes registered by the plugin.
- Anomalous spikes in gift card balance changes or order-related actions originating from a small set of IP addresses.
Detection Strategies
- Review WordPress and web server access logs for requests to GIFT4U plugin actions that lack a valid authenticated session cookie or nonce.
- Audit gift card database tables for records created or altered outside normal business workflows.
- Correlate WooCommerce order events with plugin-level actions to identify state changes that bypass expected checkout flows.
Monitoring Recommendations
- Enable verbose logging for WordPress REST API and AJAX endpoints associated with the GIFT4U plugin.
- Forward WordPress, PHP, and web server logs to a centralized SIEM or data lake for correlation and long-term retention.
- Alert on repeated 200-status requests to plugin endpoints from IPs that never authenticate.
How to Mitigate CVE-2026-57324
Immediate Actions Required
- Identify all WordPress sites running the GIFT4U Gift Cards All-in-One for WooCommerce plugin at version 1.0.10 or earlier.
- Update the plugin to a version above 1.0.10 once the vendor publishes a fix.
- If a patched version is not yet available, deactivate and remove the plugin until a fix is released.
Patch Information
Consult the Patchstack WordPress Vulnerability Report for the current patch status and fixed version guidance. Apply the vendor-released update as soon as it becomes available and confirm the plugin version after deployment.
Workarounds
- Restrict access to plugin endpoints at the web application firewall (WAF) by blocking unauthenticated requests to known GIFT4U routes.
- Limit administrative and AJAX endpoints to trusted IP ranges where feasible.
- Disable gift card functionality in production until the plugin can be patched or replaced.
