CRITICAL 9.1REMOTEUPGRADE

CVE-2024-27302 is a critical-severity flaw (CVSS 9.1) affecting go-zero. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

go-zero is a web and rpc framework. Go-zero allows user to specify a CORS Filter with a configurable allows param - which is an array of domains allowed in CORS policy. However, the `isOriginAllowed` uses `strings.HasSuffix` to check the origin, which leads to bypass via a malicious domain. This vulnerability is capable of breaking CORS policy and thus allowing any page to make requests and/or retrieve data on behalf of other users. Version 1.4.4
