An attacker can send crafted requests that result in the plugin executing unintended database queries. This could allow the attacker to read, modify, or delete site data, compromising confidentiality, integrity, and potentially availability of the application. The weakness matches CWE\u201189.", "risk_and_exploitability": "The CVSS base score of 7.6 indicates high severity, while the EPSS score of less than 1\u202f% suggests the exploit is not yet widely used. The vulnerability is not listed in the CISA KEV catalog. The likely attack vector is through HTTP requests to the plugin\u2019s endpoints, meaning an unauthenticated remote attacker could trigger the injection if the site is publicly accessible. Given the sensitivity of database operations, the risk to systems is significant if the plugin remains active."}}}}, "created": "2026-04-08T19:43:23.923444+00:00", "updated": "2026-04-14T16:40:11.061224+00:00", "vendors": ["wordpress", "wordpress$PRODUCT$wordpress", "wpmu_dev_-_your_all-in-one_wordpress_platform", "wpmu_dev_-_your_all-in-one_wordpress_platform$PRODUCT$broken_link_checker"]}
