Summary

JetBrains IntelliJ IDEA before 2026.3 lets database connections be established in untrusted projects. The flaw is an inclusion of functionality from an untrusted control sphere (CWE-829). A local attacker with no privileges needs a user to interact with a crafted project, and the impact is limited to low confidentiality and integrity loss.
