CVE-2022-46826

Arbitrary file read via built-in web server traversal

Published Dec 8, 2022 · Updated Apr 23, 2025

Path traversal in JetBrains IntelliJ IDEA before 2022.3 allows local users to read arbitrary files via the built-in web server. The server fails to constrain requested paths to the project or document root, allowing traversal outside the intended directory. Exploitation requires local access to the IDE's server and results in confidentiality loss without file modification or service interruption.
