angular angular UPGRADE

Affected: >= 19.0.0 and <= 19.2.25 · >= 20.0.0 and < 20.3.30 · >= 21.0.0 and < 21.2.22 · >= 22.0.0 and < 22.1.4

Fixed in: 20.3.30, 21.2.22, 22.1.4

Safe to downgrade to: a release before 19.0.0

1. Check installed version

npm ls angular

2. UPGRADE to 20.3.30

npm install angular@">=20.3.30"

3. If no update is available yet, DOWNGRADE to a release before 19.0.0

npm view angular versions npm install angular@"<19.0.0"

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.
