Victim activity disclosure via unbound OAuth callback
Published Aug 7, 2026 · Updated Aug 7, 2026
Login CSRF in Estatik Real Estate Plugin before 4.3.3 allows remote attackers to force a victim's browser into an attacker account. The OAuth callback exchanges an attacker-supplied Facebook or Google authorization code and issues a WordPress login cookie without state or nonce tied to the victim's session. Social login must be enabled with valid OAuth credentials, the attacker must hold a matching registered account, and the victim must open the crafted callback before the code expires; later activity becomes readable from that account.
