Because the plugin fails to enforce proper permissions, a malicious user can potentially read, modify, or delete reviews and other managed content. This flaw directly undermines the confidentiality and integrity of site data within WordPress sites that use affected plugin versions.\n", "risk_and_exploitability": "The CVSS score of 5.3 indicates a medium severity, while the EPSS score of less than 1% suggests a low likelihood of current exploitation. The vulnerability is not listed in the CISA KEV catalog. Because the plugin is accessed via the WordPress web interface, the attack vector is inferred to be remote and network based, potentially allowing attackers to target the site over the internet. Exploitation requires the ability to access the plugin\u2019s administrative functionality, which may be limited by existing permissions on the site.\n"}}}}, "created": "2026-04-08T19:28:27.362745+00:00", "updated": "2026-04-10T09:40:46.642798+00:00", "vendors": ["roxnor", "roxnor$PRODUCT$wp_ultimate_review", "wordpress", "wordpress$PRODUCT$wordpress"]}
