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/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...

Traefik is an open source HTTP reverse proxy and load balancer. From 3.6.11 until 3.6.25 and 3.7.10, Traefik's BasicAuth middleware in pkg/middlewares/auth/basicauth.go deduplicates concurrent password checks with a singleflight key built from the delimiter-free concatenation of password and...

GHSA-3Q9R-P662-5J8M Traefik: ForwardAuth middleware leaks X-Forwarded-Port spoofing via untrusted X-Forwarded-Proto when trustForwardHeader=false

Summary There is a medium severity vulnerability in Traefik's ForwardAuth middleware. Even when configured with trustForwardHeader: false, Traefik derives the X-Forwarded-Port header sent to the authentication service from the original incoming request instead of the sanitized forwarded request. ...
