github.com/gorilla/csrf improperly validates TrustedOrigins allowing CSRF attacks

CVE-2025-47909 / GHSA-82ff-hg59-8x73 / GO-2025-3884

More information

Details

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.

gorilla/csrf CSRF vulnerability due to broken Referer validation

CVE-2025-24358 / GHSA-rq77-p4h8-4crw / GO-2025-3607

More information

Details

Summary

gorilla/csrf is vulnerable to CSRF via form submission from origins that share a top level domain with the target origin.

Details

gorilla/csrf does not validate the Origin header against an allowlist. Its executes its validation of the Referer header for cross-origin requests only when it believes the request is being served over TLS. It determines this by inspecting the r.URL.Scheme value. However, this value is never populated for "server" requests per the Go spec, and so this check does not run in practice.

	// URL specifies either the URI being requested (for server
	// requests) or the URL to access (for client requests).
	//
	// For server requests, the URL is parsed from the URI
	// supplied on the Request-Line as stored in RequestURI.  For
	// most requests, fields other than Path and RawQuery will be
	// empty. (See [RFC 7230, Section 5.3](https://rfc-editor.org/rfc/rfc7230.html#section-5.3))
	//
	// For client requests, the URL's Host specifies the server to
	// connect to, while the Request's Host field optionally
	// specifies the Host header value to send in the HTTP
	// request.
	URL *[url](https://pkg.go.dev/net/url).[URL](https://pkg.go.dev/net/url#URL)

PoC

create trusted origin target.example.test protected with gorilla/csrf and served over TLS hosting form on /submit
create attacker origin attack.example.test served over TLS
attacker exfiltrates token & cookie combination from target.example.test
attacker sets exfiltrated cookie with domain=.example.test and path=/submit
- as the cookie has a more specific path than / (the default for CSRF cookies) it will be sent first by the browser on submit to our target origin
submit form from attack.example.test with exfiltrated CSRF form token
observe valid form submission as attack.example.test Origin / Referer headers are not validated.

Impact

This vulnerability allows an attacker who has gained XSS on a subdomain or top level domain to perform authenticated form submissions against gorilla/csrf protected targets that share the same top level domain.

This bug has existed in gorilla/csrf since its initial release in 2015.
