Using an implicit intent to start a service is a security risk as you can't be certain what service will respond to the intent, and the user can't see which service starts.\n2. If data within a broadcast intent may be sensitive, you should consider applying a permission to make sure that malicious applications can't register to receive those messages without appropriate permissions. In these circumstances you may also consider invoking the receiver directly rather than raising a broadcast.\n3. By default, receivers are exported and can be invoked by any other application. If your BroadcastReceiver is intended for use by other applications, you may want to apply security permissions to receivers using the <receiver> element within the application manifest.

You might want to audit every page of your application with Param Miner to flush out unkeyed inputs.\n\nOnce you've identified unkeyed inputs in your application, the ideal solution is to outright disable them. Failing that, you could strip the inputs at the cache layer, or add them to the cache key. Some caches let you use the Vary header to key unkeyed inputs, and others let you define custom cache keys but may restrict this feature to 'enterprise' customers.\n\nFinally, regardless of whether your application has a cache, some of your clients may have a cache at their end and as such client-side vulnerabilities like XSS in HTTP headers should never be ignored.",

If content type validation fails, display generic errors to the client like _\u201cInvalid Data retrieved\u201d_. Also ensure that the message is the same when the request fails on the backend and if invalid data is received. This will prevent the application from being abused as distinct error messages will be absent for closed and open ports. Under no circumstance should the raw response received from the remote server be displayed to the client.\n2. **Response Handling:** Validating responses received from remote resources on the server side is the most basic mitigation that can be readily implemented. If a web application expects specific content type on the server, programmatically ensure that the data received satisfies checks imposed on the server before displaying or processing the data for the client.\n3. **Disable unwanted protocols:** Allow only `http` and `https` to make requests to remote servers. Whitelisting these protocols will prevent the web application from making requests over other protocols like `file:///`, `gopher://`, `ftp://` and other URI schemes.\n4. **Blacklist IP addresses:** Internal IP addresses, localhost specifications and internal hostnames can all be blacklisted to prevent the web application from being abused to fetch data/attack these devices. Implementing this will protect servers from one time attack vectors. For example, even if the first fix (above) is implemented, the data is still being sent to the remote service. If an attack that does not need to see responses is executed (like a buffer overflow exploit) then this fix can actually prevent data from ever reaching the vulnerable device. Response handling is then not required at all as a request was never made.",

The Origin header can not be changed from JavaScript however relying on this header for Access Control checks is not a good idea as it may be spoofed outside the browser, so you still need to check that application-level protocols are used to protect sensitive data.\n2. **Access-Control-Allow-Origin** is a response header used by a server to indicate which domains are allowed to read the response. Based on the `CORS W3 Specification` it is up to the client to determine and enforce the restriction of whether the client has access to the response data based on this header.\n3. Make sure that there are no insecure configurations using a wildcard as value which looks like `Access-Control-Allow-Origin: *` as this header means all domains are allowed access to the resource. \n4. Make sure that when the server returns back the Origin header that there are additional checks so that access of sensitive data is not allowed.\n5. The `Access-Control-Request-Method` header is used when a browser performs a preflight `OPTIONS` request and let the client indicate the request method of the final request. On the other hand, the `Access-Control-Allow-Method` is a response header used by the server to describe the methods the clients are allowed to use.\n6. **Access-Control-Request-Headers & Access-Control-Allow-Headers:** These two headers are used between the browser and the server to determine which headers can be used to perform a cross-origin request.\n7. **Access-Control-Allow-Credentials:** This header as part of a preflight request indicates that the final request can include user credentials.\n8. **Input validation:** XMLHttpRequest L2 (or XHR L2) introduces the possibility of creating a cross-domain request using the XHR API for backwards compatibility. This can introduce security vulnerabilities that in XHR L1 were not present. Interesting points of the code to exploit would be URLs that are passed to XMLHttpRequest without validation, specially if absolute URLS are allowed because that could lead to code injection. Likewise, other part of the application that can be exploited is if the response data is not escaped and we can control it by providing user-supplied input.\n9. **Other headers:** There are other headers involved like Access-Control-Max-Age that determines the time a preflight request can be cached in the browser, or Access-Control-Expose-Headers that indicates which headers are safe to expose to the API of a CORS API specification, both are response headers specified in the CORS W3C document.",

Passing user input into templates as parameters is normally a safe alternative.\n2.If supporting user-submitted templates is a business requirement, consider using a simple logic-less template engine such as Mustache or one provided by the native language like Python's Template. If this is not an option, review the chosen template engine's documentation for hardening advice, and consider rendering the template within a sandboxed execution environment.",
