Changeset 59595 for trunk/src/wp-includes/user.php

Timestamp:

01/09/2025 07:41:47 PM (22 months ago)

Author:

Message:

Login and Registration: Check that the $_POST values are strings in wp_signon().

This prevents a fatal error from trim() via wp_authenticate() if an array is passed instead.

Follow-up to [6643], [58093].

Props leedxw, audrasjb, SergeyBiryukov.
Fixes #62794.
