egoist tsup DOWNGRADE

Affected: 8.3.4

Fixed in: no fixed release known

Safe to downgrade to: a release before 8.3.4

npm ls tsup

2. No fixed release: DOWNGRADE to a release before 8.3.4

npm view tsup versions npm install tsup@"<8.3.4"

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.
