User display-name modification via missing nonce validation
Published Nov 12, 2023 · Updated Apr 28, 2026
Cross-site request forgery in Force First and Last Name as Display Name 1.2 and earlier allows remote attackers to alter user display names. The bulk “Update Existing Users” admin action accepts a request without verifying a WordPress nonce and rewrites existing users' display_name values from stored names or usernames. Exploitation requires a logged-in administrator to visit or submit attacker-controlled content; the bounded consequence is unwanted modification of public display names.
