Advisory
Source description from Wordfence Intelligence, credited to tiborisaak.
The Ultimate Member plugin for WordPress is vulnerable to Account Takeover via Password Reset Link Disclosure in all versions up to and including 2.11.4. This is due to a chain of three logic bugs: (1) an MD5 hash fallback in get_directory_by_hash() that allows any post to be used as a member directory by computing SUBSTRING(MD5(post_id), 11, 5), (2) a strstr() parsing logic flaw in post_data() that allows bypassing WordPress's protected meta key restrictions by placing '_um_' anywhere in the meta key name rather than at the start, and (3) missing field name validation in build_user_card_data() that allows arbitrary field names including 'password_reset_link' to be passed to um_filtered_value(). This makes it possible for authenticated attackers with Contributor-level access and above to create a malicious post via XMLRPC with crafted meta fields, use the MD5 fallback to point the member directory AJAX handler to their post, inject 'password_reset_link' into the tagline_fields configuration, and leak live password reset URLs for all users in the member directory response, including administrators.
