high Nessus Plugin ID 312365

Synopsis

The integrated development environment installed on the remote host is affected by an arbitrary file read vulnerability.

Description

The version of JetBrains IntelliJ IDEA installed on the remote host is prior to 2024.3.7.1, 2025.1.7.1, 2025.2.6.2, 2025.3.4.1, or 2026.1.1. It is, therefore, affected by an arbitrary local file read vulnerability:

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to JetBrains IntelliJ IDEA version 2024.3.7.1, 2025.1.7.1, 2025.2.6.2, 2025.3.4.1, 2026.1.1 or later.
