CVE-2024-10528: ultimate member vulnerability

What is known

The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to unauthorized profile picture updates due to a missing capability check on the wp_ajax_um_resize_image() and ajax_resize_image() functions in all versions up to, and including, 2.8.9. This makes it possible for authenticated attackers, with subscriber-level access and above, to update the profile pictures of other users.

Business impact

Successful exploitation of CVE-2024-10528, a medium vulnerability (CVSS 4.3) affecting ultimate member, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether ultimate member is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation.
