axios axios UPGRADE

Affected: >= 1.0.0 and < 1.16.0

Fixed in: 1.16.0

Safe to downgrade to: a release before 1.0.0

1. Check installed version

npm ls axios

2. UPGRADE to 1.16.0

npm install axios@">=1.16.0"

3. If no update is available yet, DOWNGRADE to a release before 1.0.0

npm view axios versions npm install axios@"<1.0.0"

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.
