FKIE_CVE-2024-27302

Vulnerability from fkie_nvd - Published: 2024-03-06 19:15 - Updated: 2026-06-17 07:19
Severity
9.1 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
Summary
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 fixes this issue.
