Unauthenticated privilege escalation via forged JWTs
Published Sep 11, 2025 · Updated Apr 8, 2026
Privilege escalation in BeyondCart Connector 1.4.2 through 3.0.1 allows remote attackers to assume any WordPress user identity via JWTs. The determine_current_user filter accepts attacker-forged tokens because JWT validation relies on an exposed hard-coded secret and inadequately authorizes the claimed user. No authentication is required; successful exploitation grants the permissions of the impersonated account, including an Administrator account.
