simple-git project simple-git UPGRADE

Affected: >= 3.15.0 and < 3.36.0

Fixed in: 3.36.0

Safe to downgrade to: a release before 3.15.0

1. Check installed version

npm ls simple-git

2. UPGRADE to 3.36.0

npm install simple-git@">=3.36.0"

3. If no update is available yet, DOWNGRADE to a release before 3.15.0

npm view simple-git versions npm install simple-git@"<3.15.0"

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.
