CVE-2026-34714

Vim before 9.2.0272 allows code execution that happens immediately upon opening a crafted file in the default configuration, because %{expr} injection occurs with tabpanel lacking P_MLE.

What this means for your business

  • It affects Vim. It matters if your company, or a supplier that handles your data, runs it.
  • An attacker can use it only with access to the machine itself, without a login, and without anyone at your company clicking anything.
  • FIRST's prediction model gives it a 0.6% chance of attack attempts being seen in the next 30 days, ranking above 46% of all known flaws.

What to do

  1. 1Check whether your company or your suppliers run Vim, and which version. The affected versions are listed further down this page.
  2. 2If you do, apply the vendor's fix. A patch or vendor advisory has been published.
