CVE-2024-9529 – Secure Custom Fields < 6.3.6.3 - Admin+ Remote Code Execution

https://notcve.org/view.php?id=CVE-2024-9529

The Secure Custom Fields WordPress plugin before 6.3.9, Secure Custom Fields WordPress plugin before 6.3.6.3, Advanced Custom Fields Pro WordPress plugin before 6.3.9 does not prevent users from running arbitrary functions through its setting import functionalities, which could allow high privilege users such as admin to run arbitrary PHP functions. The Advanced Custom Fields (ACF) plugin for WordPress is vulnerable to limited arbitrary function calls via the 'register_meta_box_cb' and 'meta_box_cb' parameters in all versions up to, and including, 6.3.8 (excluding 6.3.6.2) due to insufficient input validation on those parameters. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary functions, like WordPress functions, in custom post types that will execute whenever a user accesses the injected post type. This can be leveraged to trick other users like administrators accessing posts into performing unauthorized actions through functions, and is not a very serious risk for the vast majority of site owners. Please follow the reference listed in this vulnerability record for instructions on how to update to the latest version of ACF that patches this issue and ensures accessibility to updates moving forward. • https://wpscan.com/vulnerability/dd3cc8d8-4dff-47f9-b036-5d09f2c7e5f2 • CWE-94: Improper Control of Generation of Code ('Code Injection') •
