Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly mitigates the lack of validation on 'send_to', 'product_title', 'wlmessage', and 'wlemail' parameters, preventing CRLF injection (CWE-93) and arbitrary email relay abuse via the AJAX endpoint.

AC-3 Access Enforcement good match

prevent

Enforces logical access controls requiring authentication for the unauthenticated 'woolentor_suggest_price_action' AJAX endpoint, blocking remote exploitation by attackers with no privileges.

SI-15 Information Output Filtering partial match

prevent

Filters malicious content and CRLF sequences in email outputs generated from unvalidated AJAX parameters prior to transmission, reducing the impact of relay abuse.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1566 Phishing Initial Access

Adversaries may send phishing messages to gain access to victim systems.

Why these techniques?

Direct remote exploitation of public-facing WordPress plugin (T1190); abuse enables arbitrary email relay for phishing/spam campaigns (T1566).

NVD Description

The ShopLentor – WooCommerce Builder for Elementor & Gutenberg +21 Modules – All in One Solution plugin for WordPress is vulnerable to Email Relay Abuse in all versions up to, and including, 3.3.2. This is due to the lack of…

validation on the 'send_to', 'product_title', 'wlmessage', and 'wlemail' parameters in the 'woolentor_suggest_price_action' AJAX endpoint. This makes it possible for unauthenticated attackers to send arbitrary emails to any recipient with full control over the subject line, message content, and sender address (via CRLF injection in the 'wlemail' parameter), effectively turning the website into a full email relay for spam or phishing campaigns.

Deeper analysisAI

CVE-2026-1714 affects the ShopLentor – WooCommerce Builder for Elementor & Gutenberg +21 Modules – All in One Solution plugin for WordPress, in all versions up to and including 3.3.2. The vulnerability enables Email Relay Abuse due to insufficient validation of the 'send_to', 'product_title', 'wlmessage', and 'wlemail' parameters in the 'woolentor_suggest_price_action' AJAX endpoint. This issue, classified under CWE-93 (Improper Neutralization of CRLF Sequences), has a CVSS v3.1 base score of 8.6 (AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N), indicating high severity with network accessibility, low complexity, no privileges required, no user interaction, changed scope, high integrity impact, and no confidentiality or availability impact.

Unauthenticated attackers can exploit this vulnerability remotely by sending crafted requests to the AJAX endpoint. They gain full control over email recipients via 'send_to', subject lines via 'product_title', message content via 'wlmessage', and sender addresses via CRLF injection in the 'wlemail' parameter. This effectively transforms the affected WordPress site into an open email relay, allowing attackers to conduct spam or phishing campaigns by relaying arbitrary emails to any target.

The provided references point to specific lines in the plugin's source code, including lines 170, 189, and 192 of classes/class.ajax_actions.php in tags/3.3.1 and the trunk branch, highlighting the locations where the unvalidated parameters are processed. No explicit patch or mitigation details are detailed in the available information.
