Routine

MEDIUM 6.5UPGRADE

CVE-2026-57453 is a medium-severity flaw (CVSS 6.5) affecting vim. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Vim is an open source, command line text editor. From 9.1.1784 until 9.2.0678, when the bundled zip plugin autoload/zip.vim falls back to PowerShell to browse, read, extract, update or delete entries in a zip archive, it builds the PowerShell command by inserting archive entry names that are quoted only for the shell, not for PowerShell. A crafted entry name can break out of the intended string context and cause PowerShell to execute arbitrary co

vim vim UPGRADE

Affected: >= 9.1.1784 and < 9.2.0678

Fixed in: 9.2.0678

Safe to downgrade to: a release before 9.1.1784

1. Check installed version

apt-cache policy vim || rpm -q vim || vim --version

2. UPGRADE to 9.2.0678 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade vim

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade vim

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 9.1.1784 (Debian / Ubuntu)

apt-cache madison vim sudo apt install vim=<VERSION_BEFORE_9.1.1784> sudo apt-mark hold vim

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list vim sudo dnf downgrade vim-<VERSION_BEFORE_9.1.1784> sudo dnf versionlock add vim

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
