JetBrains WebStorm < 2026.2.4 Multiple Vulnerabilities

critical Nessus Plugin ID 379716

Synopsis

The integrated development environment installed on the remote host is affected by multiple vulnerabilities.

Description

The version of JetBrains WebStorm installed on the remote host is prior to 2026.2.4. It is, therefore, affected by multiple vulnerabilities:

 - In JetBrains IntelliJ IDEA, PyCharm, PhpStorm, RubyMine, WebStorm, GoLand and Rider before 2026.3 and 2026.2.4, the jetbrainsd daemon trusted compromised intermediate certificates. (CVE-2026-118697)

 - In JetBrains WebStorm before 2026.3, 2026.2.4 code execution was possible in untrusted projects via the Angular CLI schematics loader. (CVE-2026-123322)

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 WebStorm version 2026.2.4, 2026.3 or later.
