CVE-2024-52436Network attack vector

Blind SQL injection via unparameterized email-log search

Published Nov 18, 2024 · Updated Apr 28, 2026

Blind SQL injection in WPExperts Post SMTP 2.9.9 and earlier allows remote authenticated users to read data through email-log search. The administrative search incorporates user-controlled text into a SQL LIKE query without sufficient parameterization. Administrator access to the WordPress dashboard is required, and the blind response channel exposes query-derived database information rather than direct result rows.
