CVE-2026-17603
NVD: Nexus Repository 3 did not sufficiently restrict which HikariCP connection-pool properties could be set through the DataStore configuration API. NVD: A user holding the nx-datastores-update permission could set the connectionInitSql property to execute arbitrary SQL against the configured database on every new connection. NVD: On the default H2 database backend, this could be leveraged to achieve remote code execution as the Nexus process user.
