CVE-2025-47909— Improper validation of TrustedOrigins allows CSRF attacks in github.com/gorilla/csrf

Improper validation of TrustedOrigins allows CSRF attacks in github.com/gorilla/csrf

Hosts listed in TrustedOrigins implicitly allow requests from the corresponding HTTP origins, allowing network MitMs to perform CSRF attacks. After the CVE-2025-24358 fix, a network attacker that places a form at http://example.com can't get it to submit to https://example.com because the Origin header is checked with sameOrigin against a synthetic URL. However, if a host is added to TrustedOrigins, both its HTTP and HTTPS origins will be allowed, because the schema of the synthetic URL is ignored and only the host is checked. For example, if an application is hosted on https://example.com and adds example.net to TrustedOrigins, a network attacker can serve a form at http://example.net to perform the attack. Applications should migrate to net/http.CrossOriginProtection, introduced in Go 1.25. If that is not an option, a backport is available as a module at filippo.io/csrf, and a drop-in replacement for the github.com/gorilla/csrf API is available at filippo.io/csrf/gorilla.

Google Golang 安全漏洞

Google Golang是美国谷歌（Google）公司的一种静态强类型、编译型语言。Go的语法接近C语言，但对于变量的声明有所不同。Go支持垃圾回收功能。Go的并行模型是以东尼·霍尔的通信顺序进程（CSP）为基础，采取类似模型的其他语言包括Occam和Limbo，但它也具有Pi运算的特征，比如通道传输。 Google Golang存在安全漏洞，该漏洞源于TrustedOrigins中主机列表允许HTTP请求，可能导致跨站请求伪造攻击。
