Lifecycle Timeline
5DescriptionCVE.org
The WPC Order Tip for WooCommerce WordPress plugin before 3.3.1 does not perform authorisation or nonce checks in one of its reporting features, allowing unauthenticated attackers to retrieve sensitive order data belonging to any customer of the store, such as billing names, order IDs and statuses, fee amounts and order dates.
AnalysisAI
WPC Order Tip for WooCommerce plugin (all versions before 3.3.1) exposes sensitive customer order data to unauthenticated remote attackers via an unprotected reporting feature that performs no authorization or nonce verification. Any unauthenticated party with network access to the WordPress store can query the endpoint and retrieve billing names, order IDs, statuses, fee amounts, and order dates for any customer. No public exploit or active exploitation (CISA KEV) has been identified at time of analysis; EPSS sits at the 4th percentile, indicating low current exploitation activity despite a high CVSS score.
Technical ContextAI
The vulnerability resides in the WPC Order Tip for WooCommerce WordPress plugin, an add-on for the WooCommerce e-commerce platform. WordPress plugins commonly register AJAX handlers or REST endpoints; the root cause here (CWE-200: Exposure of Sensitive Information to an Unauthorized Actor) is the complete absence of WordPress nonce validation and capability/authorization checks on at least one reporting handler. Nonces are WordPress's CSRF tokens used to verify request authenticity, while capability checks (e.g., current_user_can()) gate access to privileged data. Omitting both means any HTTP client - authenticated or not - can invoke the handler and receive order-level PII. Affected CPE: WPC Order Tip for WooCommerce versions 0 through before 3.3.1.
RemediationAI
Update the WPC Order Tip for WooCommerce plugin to version 3.3.1 or later, which introduces proper authorization and nonce verification on the affected reporting endpoint. The fix is confirmed available per the vendor; details are in the WPScan advisory at https://wpscan.com/vulnerability/ff675d0a-03f2-4309-830c-0e96e1d95a62/ and NVD at https://nvd.nist.gov/vuln/detail/CVE-2026-18357. If immediate patching is not possible, a compensating control is to disable the plugin entirely until patched - this removes the vulnerable endpoint at the cost of losing order tip reporting functionality. Alternatively, a WAF rule blocking unauthenticated requests to the specific AJAX action or REST route registered by the plugin's reporting feature can reduce exposure, though the precise endpoint identifier must be confirmed from plugin source code. There are no known side effects to upgrading to 3.3.1 beyond resolving the vulnerability.
