The issue exists in the plugin distributed through the WordPress plugin repository under the vendor beyondcart.", "description_and_impact": "The vulnerability stems from improper handling of the JWT secret and the absence of authorization checks in the determine_current_user filter within BeyondCart Connector versions 1.4.2 through 3.0.1. An unauthenticated attacker can forge a valid JSON Web Token and impersonate any existing user on a WordPress site, gaining full access to that user\u2019s privileges. This allows the attacker to read, modify, or delete data, and to perform administrative actions without authenticating, matching CWE\u2011798.", "risk_and_exploitability": "The CVSS score of 9.8 indicates critical severity, while the EPSS score of less than 1% suggests a very low exploitation probability at this time. The vulnerability is not listed in CISA\u2019s KEV catalog. Given that the flaw requires an unauthenticated attacker to craft a valid token, the likely attack vector involves sending a forged JWT in HTTP requests to endpoints that invoke the determine_current_user filter. No additional prerequisites beyond accessing the WordPress site are required."}}}}, "created": "2025-09-12T08:03:03.065451+00:00", "updated": "2026-04-20T22:00:11.191548+00:00", "vendors": ["wordpress", "wordpress$PRODUCT$wordpress"]}
