A malicious actor can access or manipulate resources that should be protected, potentially viewing or altering sensitive user data. This could lead to data disclosure, site defacement, or privileged operations within the WordPress site. The weak point is classic broken access control.", "risk_and_exploitability": "The CVSS score is not provided, but the absence of authorization grants attackers the ability to act with elevated privileges, making this a significant risk. EPSS is not available and the vulnerability is not listed in KEV, so precise exploitation likelihood is uncertain but the vulnerability\u2019s nature makes attack probable. The likely attack vector is through web requests to the plugin\u2019s endpoints, since the missing checks can be triggered by crafted URLs or form submissions. Because the flaw exists at the application layer, it can be exploited remotely by anyone who can send HTTP requests to the affected site."}}}}, "created": "2026-04-08T19:28:13.975817+00:00", "updated": "2026-04-08T19:41:16.923362+00:00", "vendors": ["ultimatemember", "ultimatemember$PRODUCT$ultimate_member", "wordpress", "wordpress$PRODUCT$wordpress"]}
