CVE-2026-76835 OAuth2 Proxy 7.15.2 through 7.15.4 Authentication Bypass via X-Forwarded-Uri Under the Default Trusted Proxy Set

OAuth2 Proxy honours a client-supplied X-Forwarded-Uri header when deciding whether a request may skip authentication, because the guard added for CVE-2026-40575 is inert in the default reverse-proxy configuration. GetRequestURI in pkg/requests/util/util.go prefers that header over the real reque...

CVE-2026-76835

OAuth2 Proxy versions 7.15.2 through 7.15.4 are affected by an authentication bypass via the X-Forwarded-Uri header. When reverse-proxy mode is enabled without trusted_proxy_ip configured, buildTrustedProxyNetSet falls back to 0.0.0.0/0 and ::/0, treating every client as a trusted proxy. An unaut...

kernel: rtmutex: Use waiter::task instead of current in remove_waiter()

A flaw was found in the Linux kernel. When the kernel's real-time mutex rtmutex component performs a specific operation called 'proxy-lock rollback' during futex requeue, it incorrectly handles task pointers. This can lead to a 'Use-After-Free' UAF vulnerability, where the system attempts to use...

CVE-2026-57216

A flaw was found in RabbitMQ, a messaging and streaming broker. The AMQP 0-9-1, AMQP 1.0, and Stream Protocol authentication mechanisms incorrectly perform a loopback check. This allows a user, typically restricted to loopback connections such as a guest user, to connect remotely. This occurs whe...

grafana: Grafana Auth Proxy: Unauthorized access due to incorrect IPv6 allow-list default

A flaw in Grafana's Auth Proxy IPv6 allow-list incorrectly defaults to a broad /32 subnet mask instead of a strict /128. This misconfiguration allows remote attackers to bypass access restrictions, potentially leading to unauthorized access and data manipulation...

FreeRDP: FreeRDP: HTTP Proxy Request Injection via Redirection

A flaw was found in FreeRDP. A malicious or compromised Remote Desktop Protocol RDP server can exploit this vulnerability to inject arbitrary headers or requests into an HTTP proxy CONNECT request. This occurs because FreeRDP does not properly validate control characters in the server-controlled...

CVE-2026-56865

A flaw was found in golang.org/x/mod/sumdb/tlog. A malicious Go proxy GOPROXY could exploit this vulnerability by forging sumdb tiles. This allowed the proxy to bypass integrity checks and serve malicious module content to a local Go module cache, which would then go undetected by the transparenc...
