CVE-2026-11487Public exploit

Ex command execution via unescaped View filename

Published Jun 8, 2026 · Updated Jun 8, 2026

Command injection in Neovim 0.12.0 through 0.12.2 allows local users to execute Ex commands through a crafted filename. In vim.secure.read, the View branch appends the unescaped path to an sview command, so a pipe in the filename is parsed as an Ex command separator. Exploitation requires control of a local filename and selection of View at the trust prompt; injected Ex commands run with the Neovim process's access.
