Changeset 60681 for trunk/src/wp-admin/includes/post.php

Timestamp:

Message:

Scripts: Use appropriate JSON encoding flags for script tags.

wp_json_encode() with default arguments is insufficient to safely escape JSON for script tags. Use JSON_HEX_TAG | JSON_UNESCAPED_SLASHES flags.

Developed in ​https://github.com/WordPress/wordpress-develop/pull/9557.
