In this mode the server binds to `0.0.0.0` and exposes the MCP `/mcp` endpoint without an MCP-layer authentication check. Any network client that can reach the port can initialize a session, list tools, and call tools that read LINE Desktop chat history or send LINE messages through the already logged-in desktop application.\n\nThis is High for deployments where the HTTP port is reachable beyond the local host, because the server acts with the user authority of the logged-in LINE Desktop session. It is lower if the listener is strictly firewalled to trusted local clients.\n\n## Affected version\n\nRepository: `dtwang/line-desktop-mcp`\n\nCurrent source checked: `fbed0d2d3048e63f48a356a1267ed8ec5e78f3ae` on `main`, committed 2026-05-14.\n\nPublished npm package checked: `line-desktop-mcp@1.1.1`.\n\n## Source evidence\n\n`README.md` documents Streamable HTTP mode:\n\n```text\nnpx line-desktop-mcp@latest --http-mode --port 3000\n```\n\nThe same README documents MCP endpoints at `/mcp` and explains that t","public_affected_ranges":["<= 1.1.1"]}],"null_published_at":"2026-11-05T19:10:21.431Z","source_updated_at":"2026-06-26T21:50:51.000Z","source_disclosed_at":"2026-06-26T21:50:49.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-05T19:05:04.022Z"}],"next_cursor":null,"snapshot_revision":"42594"}
