This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload persists in wp_comments.comment_author independently of the user account, so removing or changing the attacker's display name after the comment is posted does not neutralize the stored script.\n\n## Affected\n\n- `user_profile_builder_beautiful_user_registration_forms_user_profiles_user_role_editor <= 4.0.3`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":35,"depthScoreParts":{"impact":35.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
