Advisory
Source description from Wordfence Intelligence, credited to Fariq Fadillah Gusti Insani (fariqfgi).
The Yoast SEO plugin for WordPress is vulnerable to Sensitive Data Exposure in versions up to, and including, 17.2 via the /wp/v2/posts REST endpoints that discloses the full internal path of featured images from posts. This makes it possible for unauthenticated attackers to extract sensitive data which consists of full site path information which can be used to exploit other vulnerabilities.
