AI Analysis
Technical Summary
CVE-2026-11487 is a command injection vulnerability affecting Neovim up to version 0.12.2. The issue exists in the M.read function of the file runtime/lua/vim/secure.lua, part of the View Branch component. By manipulating the path argument, an attacker with local access can execute arbitrary commands on the host. The vulnerability is exploitable locally and a patch has been developed (commit f83e0dcaf8cf18de94828341b0a1a61a86c75baf) to remediate the flaw. No official vendor advisory or patch release details are provided in the data, so patch status should be verified with the vendor.
Potential Impact
An attacker with local access can exploit this vulnerability to perform command injection, potentially executing arbitrary commands with the privileges of the Neovim process. This could lead to unauthorized actions on the affected system. The CVSS score of 4.8 indicates a medium severity impact, reflecting the local attack vector and required privileges.
Mitigation Recommendations
A patch identified by commit f83e0dcaf8cf18de94828341b0a1a61a86c75baf has been created to fix this vulnerability. Users of Neovim versions 0.12.0, 0.12.1, and 0.12.2 should apply this patch or upgrade to a fixed version once available. Patch status is not explicitly confirmed in the provided data; therefore, users should consult the official Neovim repository or vendor advisory for the latest remediation guidance.
