CVE-2022-29812

Code deception via inadequate directionality warnings

Published Apr 28, 2022 · Updated Aug 3, 2024

Improper Unicode handling in JetBrains IntelliJ IDEA before 2022.1 allows local users to disguise source-code behavior with directionality controls. The editor notification mechanism does not adequately flag files containing Unicode directionality formatting characters, so displayed token order can differ from logical order. A user must open and trust attacker-influenced source text; the resulting visual deception can conceal an integrity-affecting code change.
