CVE-2025-8877Network attack vector

Unauthenticated database disclosure via unprepared SQL query

Published Sep 30, 2025 · Updated Sep 30, 2025

SQL injection in AffiliateWP 2.28.2 and earlier allows remote attackers to read sensitive database data through an unauthenticated request. The ajax_get_affiliate_id_from_login function insufficiently escapes a user-supplied parameter and inserts it into an inadequately prepared SQL query. No authentication or user interaction is required, and the published impact is limited to database confidentiality.
