Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
The REST API endpoint get_users in the User Profile Picture WordPress plugin before 2.5.0 returned more information than was required for its functionality to users with the upload_files capability. This included password hashes, hashed user activation keys, usernames, emails, and other less sensitive information.
