Pensar - auto fix for 2 issues (CWE-20, CWE-20)

[pensarapp]

I fixed two security vulnerabilities in the file:

1. Input Validation in createNewPost and updatePostAction:

   • Added a helper function validateObject to check if inputs are valid objects
   • Added validation before passing untrusted data to sensitive operations
   • For createNewPost: Added validation to ensure the post parameter is a valid object
   • For updatePostAction: Added validation for both postId (ensuring it's a string) and post (ensuring it's an object)

2. Input Validation in deletePostAction:

   • Added more specific validation for the post object in deletePostAction
   • Checks that post exists, is an object, has an 'id' property, and that the id is a string
   • This prevents malformed or malicious input from being passed to the database deletion operation

These changes address the CWE-20 (Improper Input Validation) vulnerabilities by ensuring that all user-supplied inputs are properly validated before being used in sensitive operations. The validation prevents potential injection attacks or unexpected behavior that could occur when processing malformed data.

More Details

Type	Identifier	Message	Severity	Link
Application	CWE-20	The function 'createNewPost' takes in a 'post' object from an external source and passes it directly to the simplcms.posts.createPost method without visible input validation or sanitization. This may lead to potential injection attacks or data integrity issues if the input is not validated within the 'createPost' method. The risk might be mitigated if validation is done in lower layers, but as it stands this code shows an unvalidated trust boundary crossing. This analysis flags it under CWE-20 (Improper Input Validation).	medium	Link
Application	CWE-20	The function 'deletePostAction' receives a 'post' object that is provided by an external source and passes it without additional validation to the simplcms.posts.deletePost method. Without proper input validation, there could be potential issues if unexpected input shapes are passed to the delete operation. This is flagged as CWE-20 (Improper Input Validation).	medium	Link
