v5.2.1

5.2.1 (2025-03-26)

Security

• cross-origin requests are not allowed unless allowed by Access-Control-Allow-Origin header
• requests with an IP addresses in the Origin header are not allowed to connect to WebSocket server unless configured by allowedHosts or it different from the Host header

The above changes may make the dev server not work if you relied on such behavior, but unfortunately they carry security risks, so they were considered as fixes.

Bug Fixes

• prevent overlay for errors caught by React error boundaries (#5431) (8c1abc9)
• take the first network found instead of the last one, this restores the same behavior as 5.0.4 (#5411) (ffd0b86)
