CVE-2026-3985: Creative Mail – Easier WordPress & WooCommerce Email Marketing <= 1.6.9 - Unauthenticated SQL Injection via 'checkout_uuid' Parameter
The Creative Mail – Easier WordPress & WooCommerce Email Marketing plugin for WordPress is vulnerable to SQL Injection via the 'checkout_uuid' parameter in all versions up to, and including, 1.6.9. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query in the `has_checkout_consent()` method. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
Security readout for executives and security teams
Plain-English summary
A flaw in Creative Mail versions through 1.6.9 may let anyone on the internet extract sensitive information from a WordPress database. No login or user interaction is required. The supplied sources do not establish data modification, service disruption, or active exploitation.
Executive priority
Prioritize rapid inventory and remediation for public WordPress commerce sites because exploitation requires neither credentials nor user action and may expose database information. Escalate systems holding customer, order, or marketing data. Current sources do not confirm active exploitation or identify a fixed release.
Technical view
The checkout_uuid parameter reaches an inadequately escaped and insufficiently prepared SQL query in has_checkout_consent(), enabling unauthenticated SQL injection. CVSS 3.1 scores it 7.5: network-accessible, low complexity, no privileges or interaction, with high confidentiality impact but no stated integrity or availability impact.
Likely exposure
Internet-accessible WordPress or WooCommerce sites running an active Creative Mail version up to and including 1.6.9 are potentially exposed where the affected checkout-consent functionality is reachable. The bundle does not identify required configuration details, installation counts, or a confirmed fixed version.
Exploitation context
The source bundle marks this CVE as absent from KEV and provides no cited evidence of active exploitation. Exploitation is nevertheless described as remotely reachable without authentication and capable of database information extraction. Treat exposure as credible, but do not represent exploitation in the wild as confirmed.
Researcher notes
CWE-89 applies. The cited locations point to DatabaseManager.php around line 298 and CheckoutManager.php around line 100 in version 1.6.9, plus trunk code. The bundle attributes the flaw to checkout_uuid handling in has_checkout_consent(). Fixed-version status, practical prerequisites, exploitation telemetry, and the exact data obtainable remain unconfirmed.
Mitigation direction
Inventory WordPress sites for Creative Mail and record installed and active versions.
Check vendor and WordPress plugin guidance for a confirmed fixed release or official mitigation.
Apply the vendor-confirmed update promptly when available, following normal backup and change-control procedures.
If no fix is confirmed, consider disabling the plugin after reviewing operational impact.
Monitor WordPress, database, and security logs for unusual checkout-related requests or data-access patterns.
Validation and detection
Confirm whether Creative Mail is installed, active, and version 1.6.9 or earlier.
Determine whether the affected checkout-consent functionality is reachable from unauthenticated internet requests.
Verify any installed replacement version against current vendor guidance; do not assume trunk code is released.
Review historical logs for suspicious checkout_uuid activity without attempting exploitation.
Confirm database credentials follow least privilege to limit potential information exposure.

Injection into data stores can inform collection, data access, and exfiltration detection reviews. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references database injection or access, so collection and exfiltration review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
