…pdates Adds a new configuration option GOTRUE_SECURITY_UPDATE_PASSWORD_REQUIRE_CURRENT_PASSWORD that addresses session hijacking vulnerabilities by requiring users to provide their current password when changing to a new password. When enabled, the PUT /user endpoint requires a current_password field in the request body alongside the new password. The current password is verified before allowing the password change, preventing attackers with stolen session tokens from changing passwords without knowledge of the current password. This security feature works alongside the existing UpdatePasswordRequireReauthentication option and is disabled by default for backwards compatibility. Related to discussion #32972

What is the current behavior?
When a user's session token is compromised (e.g., via XSS, MITM, or other attacks), an attacker can change the user's password without knowing the current password using the PUT
/userendpoint.We discovered this vulnerability during a penetration test of our self-hosted Supabase instance. Our internal security requirements mandate that password changes must verify the current password to prevent session hijacking attacks.
