Summary
In Uni-CLI prior to version 0.225.2, the legacy JSON-RPC-over-HTTP MCP transport was exposed on loopback without validating browser Origin headers. A malicious web page could send a CORS simple POST to the local /mcp endpoint and drive tools/call requests against the user's local Uni-CLI server.
Risk Assessment
A malicious website visited by the user could invoke tools on their local Uni-CLI server, potentially leading to unauthorized actions on the user's behalf. The issue concerns the browser-to-localhost boundary.
Recommendation
Upgrade Uni-CLI to version 0.225.2, which contains the fix. Until patched, avoid starting the local MCP HTTP transport.

SEPPmail Secure Email Gateway before 15.1.1 trusts a file path supplied in externally provided Large File Transfer attachment metadata. An unauthenticated remote sender can cause the mail-processing worker to disclose, move, or delete an accessible regular file when LFT is enabled and the message reaches an affected secure-mail processing path. The validated workers ran as root.

Original NVD description (English source)
Uni-CLI gives people and agents one command interface for websites, browsers, desktop applications, local tools, and MCP. Prior to version 0.225.2, Uni-CLI exposed the legacy JSON-RPC-over-HTTP MCP transport on loopback without validating browser Origin headers before routing requests. A malicious web page could send a CORS simple POST request, such as text/plain, to the local /mcp endpoint and deliver a JSON-RPC body to the dispatcher. If the user had started the local MCP HTTP transport, that page could drive tools/call requests against the user's local Uni-CLI server. The Streamable HTTP transport already enforced this browser-to-localhost boundary. The legacy stateless HTTP path did not, so the two HTTP transports had drifted. This issue is about the browser-to-localhost boundary; it does not change Uni-CLI's local-code-execution trust model. This issue has been patched in version 0.225.2.
