axios axios DOWNGRADE

Affected: 1.15.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.15.2

1. Check installed version

npm ls axios

2. No fixed release: DOWNGRADE to a release before 1.15.2

npm view axios versions npm install axios@"<1.15.2"

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.
