Wildcard slugs in URLs

Hello,

I’m having an issue in my urls, these create infinite URLs, for example:

For the URL, for example: https://semillarium.com/semilla-lino-marron-bio-250gr-ecosana/

You can add an slug everywhere and it loads OK:

https://semillarium.com/EXAMPLE/semilla-lino-marron-bio-250gr-ecosana/

https://semillarium.com/TRY/semilla-lino-marron-bio-250gr-ecosana/

For SEO is making me duplicate content.

Anybody could help me? Thank you!
