New description:

 WordPress core relies on several values from PHP superglobal variables. In
 some cases, these values are accessed directly without first verifying
 their existence or applying proper sanitization. This can lead to
 potential ~~security~~ //data integrity// concerns and PHP notices.

 This pull request addresses a subset of these issues by adding appropriate
 existence checks and sanitization to ensure safer and more robust handling
 of superglobal data.
