Unauthenticated account takeover via unchecked password overwrite
Published Oct 16, 2026 · Updated Oct 16, 2026
Account takeover in Theme My Login 7.2.1 and earlier allows remote attackers to replace passwords through lost-password requests. The wp_pre_insert_user_data filter accepts the user_pass1 POST parameter without first verifying the account owner's identity. Exposure requires a WordPress multisite setup in certain configurations; the public record does not specify those settings.
