CVE-2026-90898 Bifrost unauthenticated remote code execution via MCP stdio client registration

Bifrost registers MCP clients through its management API. A stdio client is a command plus args. Bifrost starts that program in the gateway the moment the client is added. No MCP handshake required. The default is governance.authconfig.isenabled=false. Auth off means every caller is a local admin...

CVE-2026-90898: Missing Authentication for Critical Function

Bifrost registers MCP clients through its management API. A stdio client is a command plus args. Bifrost starts that program in the gateway the moment the client is added. No MCP handshake required. The default is governance.authconfig.isenabled=false. Auth off means every caller is a local admin...

EUVD-2026-75780

IBM Langflow OSS 1.0.0 through 1.11.5 allows an authenticated non-administrative user could execute arbitrary operating system commands on the server at the privilege level of the application process by constructing a flow with an MCP Tools component configured to use a local stdio subprocess...

EUVD-2026-75796

IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote authenticated attacker to execute arbitrary commands due to improper validation of command-line arguments in the MCP stdio server configuration...

Linux Distros Unpatched Vulnerability : CVE-2026-88265

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A flaw was found in crun. After pivotroot, reopening /dev/null for stdio can follow a symlink and attach a host file to container stdio, then change that file's...

CVE-2026-85623

A flaw was found in goose. This vulnerability allows attackers to execute arbitrary commands by distributing malicious recipes that leverage insecure recipe standard input/output stdio extensions and retry checks. This bypasses the existing security scan, enabling the execution of shell commands...

Omnigent: Shared Agent Bundle Overwrite Leads to Authenticated Runner RCE

SummaryAn authenticated user with edit access to their own session can overwrite a shared/template agent by uploading a full agent bundle through PUT /sessions/sessionid/agent.Shared/template agents are shown as not MCP-editable, but this upload path still accepts a replacement bundle. By adding ...

PYSEC-2026-3812 Chainlit has command injection via MCP stdio transport that allows unauthenticated remote code execution

Am I affected? Only if your deployment sets features.mcp.enabled = true in .chainlit/config.toml. MCP has been disabled by default since v2.7.0, so most Chainlit deployments are not affected. No authentication is required: /mcp is reachable by any client that can open a session. Summary When MCP ...
