github.com/go-chi/chi/middleware: go-chi/chi: IP spoofing via X-Forwarded-For header manipulation

A flaw was found in the go-chi/chi component. The RealIP middleware, responsible for resolving the request source IP, does not properly validate trusted proxies when processing the X-Forwarded-For header. A remote attacker can exploit this by prepending a forged IP address to the X-Forwarded-For...

github.com/go-chi/chi: go-chi/chi: IP Spoofing via RealIP Middleware allows bypassing access controls

A flaw was found in the go-chi/chi RealIP middleware. This vulnerability allows a remote attacker to perform IP spoofing by supplying arbitrary IP addresses in client-controlled headers. This can lead to bypassing IP-based access controls, evading rate limiting and geo-IP restrictions, and...

github.com/go-chi/chi/middleware: go-chi chi: IP spoofing via X-Forwarded-For header allows bypass of access controls

A flaw was found in the go-chi chi RealIP middleware. This vulnerability allows a remote attacker to spoof their IP address by manipulating the X-Forwarded-For HTTP header. By exploiting this, an attacker can bypass IP-based access control lists and rate-limiting mechanisms, and forge log entries...

GO-2026-5777 Chi's RealIP Middleware allows IP spoofing via unvalidated X-Forwarded-For header in github.com/go-chi/chi

GHSA-3FXJ-6JH8-HVHX chi Has an IP Spoofing Vulnerability in `middleware.RealIP`

Summary The RealIP middleware in go-chi/chi is vulnerable to IP spoofing because it blindly trusts the first leftmost element of the X-Forwarded-For HTTP header. This allows a remote attacker to bypass IP-based access control lists ACLs and rate-limiting mechanisms by providing a spoofed IP addre...

Insufficient Verification of Data Authenticity

Overview Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity via the realIP function. An attacker can gain unauthorized access to restricted resources, evade rate limiting, or manipulate security logs by supplying a crafted X-Forwarded-For header...

GHSA-RJR7-JGGH-PGCP chi's RealIP Middleware allows IP spoofing via unvalidated X-Forwarded-For header

Summary realip middleware in go-chi/chi trusts headers like x-forwarded-for without checking them, so attackers can fake their ip and bypass rate limits or access controls Details the vuln is in middleware/realip.go , the realIP function pulls IPs straight from client headers and replaces...

Origin Validation Error

Overview Affected versions of this package are vulnerable to Origin Validation Error via the RealIP process. An attacker can cause misidentification of the request source IP by manipulating the X-Forwarded-For header, potentially bypassing access controls or falsifying request logs. Remediation...

chi Middleware Vulnerable to Potential IP Spoofing via `X-Forwarded-For` Header in `Request.RemoteAddr` Resolution

Summary The vulnerability allows the Request.RemoteAddr to be spoofed when determining the request source IP via the X-Forwarded-For header. This could result in misidentification of the request source and potentially compromise access control and logging integrity. Details Currently, the RealIP...

PT-2026-71986

Name of the Vulnerable Software and Affected Versions go-chi/chi versions prior to 5.3.0 Description The RealIP middleware middleware/realip.go allows IP spoofing because the realIP function reads client-controlled headers and overwrites r.RemoteAddr without verifying if the request came from a...

PT-2026-71987

Name of the Vulnerable Software and Affected Versions go-chi/chi versions 0.9.0 through 5.2.9 Description The RealIP middleware resolves the request source IP Request.RemoteAddr by using the first IP address found in the X-Forwarded-For header without validating trusted proxies. This allows a...
