CVE-2024-5639: user profile picture vulnerability

What is known

The User Profile Picture plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.6.1 via the 'rest_api_change_profile_image' function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Author-level access and above, to update the profile picture of any user.

Business impact

Successful exploitation of CVE-2024-5639, a medium vulnerability (CVSS 4.3) affecting user profile picture, 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 user profile picture 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. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
