Vim < 9.2.0597 Code Execution (GHSA-65p9-mwwx-7468)

high Nessus Plugin ID 321505

Language:

Synopsis

The remote host is missing a security update.

Description

The version of Vim installed on the remote host is prior to 9.2.0597. It is, therefore, affected by a vulnerability as referenced in the GHSA-65p9-mwwx-7468 advisory.

 - Vim's Python omni-completion executes reconstructed function and class definitions from the current buffer with exec() as part of populating the completion dictionary. Python evaluates function default values, parameter annotations, and class base expressions at definition time, so a hostile buffer can execute attacker-controlled Python expressions during omni-completion. The existing g:pythoncomplete_allow_import mitigation (GHSA-52mc-rq6p-rc7c) does not cover this path, because the attacker-controlled code is not a harvested import/from statement. (CVE-2026-52860)

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

Solution

Upgrade to Vim version 9.2.0597 or later.
