Strategic Overview

Vulnerability Overview

Unvalidated input in the Anti-Spam by CleanTalk WordPress plugin, versions before 5.149, lead to multiple authenticated SQL injection vulnerabilities, however, it requires high privilege user (admin+).

Technical Analysis

REMEDIATION: Update to version 5.149, or a newer patched version --- IDENTIFIER: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')) The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
