CVE-2022-24346

Local code execution via RLO characters

Published Feb 25, 2022 · Updated Aug 3, 2024

Improper RLO character handling in JetBrains IntelliJ IDEA before 2021.3.1 allows local users to execute code on the host. JetBrains identifies Right-to-Left Override characters as the trigger but has not disclosed the affected component or the operation that turns them into code execution. Exploitation requires local low-privilege access and runs code in the affected user's security context, enabling data access, alteration, or service interruption.
