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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.29%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
