  "details": "### Impact\n\nThe session cookie is set with `HttpOnly; SameSite=Lax; Path=/` but does not include the `Secure` flag. This means the cookie will be sent over plain HTTP connections.\n\nSince the server binds to `127.0.0.1` by default and uses HTTP (not HTTPS), this is acceptable for localhost use. However, when `--allow-network` is used to bind to `0.0.0.0`, cookies could be transmitted over insecure network connections and intercepted by an attacker.\n\n**Affected code:**\n- `packages/server/src/session.ts:76` \u2014 cookie string lacks `; Secure` attribute\n\n### Patches\n\n0.70.5\n\n**Fix:** Conditionally add `; Secure` when served over HTTPS or when `--allow-network` is enabled:\n```typescript\nconst securePart = isHttps ? \"; Secure\" : \"\";\nreturn `${SESSION_COOKIE_NAME}=${cookieValue}; HttpOnly; SameSite=Lax; Path=/${securePart}; Max-Age=${maxAge}`;\n```\n\n### Workarounds\n\nDo not use `--allow-network` over untrusted networks without a TLS-terminating reverse proxy.\n\n### Resources\n\n- OWASP: Secure Cookie Attribute\n- File: `packages/server/src/session.ts`",
