CVE-2024-24940

File overwrite via unconstrained archive entry paths

Published Feb 6, 2024 · Updated May 15, 2025

Relative path traversal in JetBrains IntelliJ IDEA before 2023.3.3 allows local users to write files outside an archive destination. The archive unpacker accepts relative entry paths without ensuring that their resolved destinations remain beneath the selected extraction directory. Exploitation requires a low-privileged user to open a crafted archive, and the vendor assessment limits the demonstrated consequence to unauthorized file modification.
