Appending digit(s) to posts, pages and attachment URLs and duplicate content

[henry.wright]

If I visit an attachment page (unattached media for example) and then append some digits to the URL, I see duplicate content.

Steps to reproduce:

1. Visit an attachment page such as example.com/slug/
2. Append some random digits to the URL:

• example.com/slug/5/
• example.com/slug/16/

You should see the same content on each page.

I did some more testing and found the problem isn't specific to attachments. You can append digit(s) to posts, pages and attachments and you'll see the same content on every page. Examples:

Unattached attachments (same content on each)

example.com/slug/
example.com/slug/5/
example.com/slug/16/
example.com/slug/544/
example.com/slug/1618/

Posts (same content on each)

example.com/2017/05/15/slug/
example.com/2017/05/15/slug/17/
example.com/2017/05/15/slug/1811/
example.com/2017/05/15/slug/19817/
example.com/2017/05/15/slug/199181/

Pages (same content on each)

example.com/slug/
example.com/slug/2/
example.com/slug/126/
example.com/slug/5144/
example.com/slug/11618/

Duplicate of #28081.

Hi @SergeyBiryukov this isn't quite the same issue as #28081. That ticket refers to URLs with /page/ in them and this ticket doesn't. I think the issues and solutions might be separate?

The current patch on #28081 might only cover one case, but I think the ultimate solution should cover both, since essentially it's the same issue. My comment there refers to non-/page/ URLs to make sure they don't get missed.

If the fix turns out to be separate, we can reopen this ticket, but the same issue has also been reported in #39183 and #39899, so either way it's a duplicate at the moment.

Thanks for the update Sergey. Glad to see you're already tracking this 👍
