Description

If we try to run the next code <scri<script></script>pt>alert("krya");</script> via the wp_strip_all_tags function it remove the script content only once. So, the next hack allows passing the script content throw the function.

## In details.

First iteration:

  • input: `<scri<script></script>pt>alert("krya");</script>
  • output: <script>alert("krya");</script>

Thankfully the strip_tags removes scripts tags later, but the content is still present.
