At a glance

CVE-2025-11691 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the PPOM WordPress plugin, affecting versions <= 33.0.15. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 33.0.16; sites on affected versions should update now. Disclosed October 2025, reported by Talal Nasraddeen.

Vulnerability Overview

The PPOM – Product Addons & Custom Fields for WooCommerce plugin for WordPress is vulnerable to SQL Injection via the PPOM_Meta::get_fields_by_id() function in all versions up to, and including, 33.0.15 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. 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. This is only exploitable when the Enable Legacy Price Calculations setting is enabled.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

PPOM <= 33.0.15 carries this weakness at get_fields_by_id(), and reaching it takes no account at all. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For PPOM the fix is 33.0.16: builds <= 33.0.15 are affected, anything from 33.0.16 onward is not.

Remediation

Update to version 33.0.16, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: PPOM 33.0.16 closes this, and updating the plugin is the step that ends it.
