When HTTP/3 is enabled and a router use...

CVE-2026-46579

A flaw was found in the OpenShift Router. When a Route has insecureEdgeTerminationPolicy set to Allow, the HTTP frontend does not remove X-SSL-Client- headers from incoming requests. This allows an unauthenticated attacker to send plain HTTP requests with crafted X-SSL-Client- headers. As a resul...

CVE-2026-0073

In adbdtlsverifycert of auth.cpp, there is a possible bypass of wireless ADB mutual authentication due to a logic error in the code. This could lead to remote proximal/adjacent code execution as the shell user with no additional execution privileges needed. User interaction is not needed for...
