Description Robb Gatica 2024-04-05 13:54:28 UTC

WordPress Core is vulnerable to Sensitive Information Exposure in versions up to, and including,  6.4.3 via the redirect_guess_404_permalink function. This can allow unauthenticated attackers to expose the slug of a custom post whose 'publicly_queryable' post status has been set to 'false'.
