CVE-2026-52858 (opens in a new tab)How to fix?
Upgrade vim/vim to version 9.2.0561 or higher.
Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection in the python3complete.vim script when the +python3 interpreter is enabled, or in the legacy pythoncomplete.vim for builds with the +python interpreter. An attacker can execute arbitrary Python code as the editing user by crafting a malicious .py file with a sibling Python package and invoking omni-completion, which causes the package's top-level code to run due to the buffer's working directory being on sys.path.
