This makes it possible for unauthenticated attackers to expose arbitrary users' sensitive profile data — including email address, display name, nicename, registration date, profile image URL, and any string-valued user meta fields such as first name, last name, nickname, description, and custom meta keys — via the REST response. Exploitation requires a published page that uses a Kirki template containing at least one user-type dynamic content block; target user IDs are enumerable via standard WordPress REST endpoints, making the only prerequisite the presence of such a template on the site.\n\n## Affected\n\n- `kirki_freeform_page_builder_website_builder_customizer <= 6.3.2`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
