"According to its self-reported version, the JetBrains PyCharm installation on the remote host is prior to 2026.1.4.
It is, therefore, affected by an arbitrary code execution vulnerability.

In JetBrains PyCharm before 2026.1.4, 2026.2 arbitrary code execution via malicious Python executable was possible on
untrusted project open.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
