FreeRDP versions before 3.31.0 contain an uninitialized heap memory disclosure vulnerability in the urbdrc USB redirection channel. A malicious RDP server can induce failing USB transfers to read uninitialized heap memory from the client, defeating ASLR and enabling remote code execution when...

CVE-2026-91949 FreeRDP 3.0.0 through 3.30.0 Protocol Negotiation Bypass

FreeRDP server versions before 3.31.0 contain a protocol negotiation bypass vulnerability that allows unauthenticated attackers to establish RDSTLS connections despite server policy disabling them. Attackers can send incompatible protocol requests, receive negotiation failures, then complete TLS...

CVE-2026-91949

FreeRDP server versions 3.0.0 through 3.30.0 (before 3.31.0 ) contain a protocol negotiation bypass vulnerability. The root cause, as described in the associated GHSA advisory (GHSA-x7v6-xfx3-52j6), is that the server continues after a negotiation failure and dispatches a failure code as RDSTLS ,...

EUVD-2026-78791

Flowise before 3.1.4 fails to enforce workspace-level authorization checks in openai-realtime endpoints, allowing authenticated users to access tools from ChatFlows in other workspaces by supplying an unscoped chatflowid. Attackers can invoke GET and POST requests to retrieve tool definitions and...

CVE-2026-91932

Flowise before 3.1.4 contains a validation bypass in its MCP server configuration that allows authenticated attackers to achieve remote code execution . The root cause is an unvalidated cwd parameter : by placing clean filenames in the args array, an attacker bypasses path validation while contro...
