CVE-2026-3405Public exploitNetwork attack vector

Authenticated file disclosure via unchecked JDBC URL

Published Mar 2, 2026 · Updated Mar 2, 2026

JDBC connection injection in ThinkGem JeeSite 5.15.0 and 5.15.1 allows remote authenticated users to read arbitrary server files. The Connection Handler accepts a user-controlled JDBC URL and driver class without validation, allowing a rogue MySQL server to request local files through LOAD DATA LOCAL INFILE. Low-privilege access is required; command execution additionally depends on an exploitable driver such as H2 being present on the classpath.
