CVE-2024-52555

Code execution via type definitions installer script

Published Nov 15, 2024 · Updated Nov 15, 2024

Code execution in JetBrains WebStorm before 2024.3 allows attackers to run code through a type definitions installer script. In Untrusted Project mode, the IDE allows that installer script to run instead of suppressing executable project-supplied behavior. Exploitation requires user interaction with an untrusted project and can disclose or alter data accessible to the WebStorm process.
