AI-suggested
Organizations should immediately review and restrict plugin usage within IntelliJ IDEA, ensuring only trusted plugins from verified sources are installed. Disable or limit automatic LSP server startup where possible until JetBrains releases an official patch in version 2025.2 or later. Implement strict access controls on developer workstations to prevent unauthorized local access and privilege escalation. Employ endpoint detection and response (EDR) solutions to monitor for unusual plugin activity or unexpected process launches related to the IDE. Conduct regular audits of installed plugins and IDE configurations to detect anomalies. Educate developers about the risks of installing untrusted plugins and the importance of maintaining updated IDE versions. Consider isolating development environments or using virtual machines to contain potential exploitation. Monitor JetBrains security advisories closely for patch releases and apply updates promptly once available.
