What is CVE-2026-15758?

The 3D FlipBook plugin for WordPress exposes sensitive information due to an insecure handling of the 'id' parameter. Attackers can exploit this vulnerability to retrieve sensitive metadata from password-protected flipbooks, including titles, outlines, and URLs of the underlying PDFs. The vulnerability can be exploited anonymously, allowing attackers to pre-enumerate flipbook post IDs and bypass existing protections, making confidential information accessible without authentication.
