Malformed discovery link results in fatal error

[WillBrubaker]

Describe the bug WordPress adds discovery links. If those discovery links are somehow malformed this will result in a fatal error when visiting that link if the theme in use loads a mini-cart.

To Reproduce

1. WooCommerce is installed and active and running on an nginx server
2. A theme which uses the WooCommerce mini-cart.php template (such as Storefront) is active
3. Visit an invalid oembed URL e.g. https://woocommerce.com/blog/wp-json/oembed/1.0/embed?url=https%3A%2F%2Fwoocommerce.com%2Fmy-dashboard%2F&format=xml
4. When the mini-cart tries to load, the WooCommerce cart has never been loaded because https://github.com/woocommerce/woocommerce/blob/3.6.5/includes/class-woocommerce.php#L550 evaluates to false
5. This results in Fatal error: Uncaught Error: Call to a member function get_cart_subtotal() on null

Expected behavior No fatals and I'd just like to point out that I notice a difference if we do the same type of steps on a site hosted on an Apache server e.g.: https://wctesting.club/blog/wp-json/oembed/1.0/embed?url=https%3A%2F%2Fwctesting.club%2Fsample-page%2F&format=xml

results in:

Isolating the problem (mark completed items with an [x]):

• [x ] I have deactivated other plugins and confirmed this bug occurs when only WooCommerce plugin is active.
• [ x] This bug happens with a default WordPress theme active, or Storefront.
• [x ] I can reproduce this bug consistently using the steps above.

@juliaamosova Is this going to get assigned to a future milestone?

[rodelgc]

As this issue is already quite dated, we'll try to reproduce this on the current released version of WooCommerce to see if this issue is still happening. I'm adding the status: needs reproduction label for the meantime.

[swatipawarGS]

Hi @WillBrubaker ,

Thank you for taking the time to report this bug, we really appreciate your help. We are able to reproduce the issue on our end using WooCommerce 6.0.0 version , WordPress 5.8.2 version and nginx server .

Please find below screenshots for reference :

Priority of this issue will be assigned shortly after we’d go through a round of prioritization. Please note it may take a couple of days.

Hi @WillBrubaker I tried to replicate this again, it didn't spawn the fatal, but instead produced a warning on another place related to the session object (log below). It does seem that not considering the oembed as a frontend request still produces nefarious side effects, I'm adding this to our backlog. As a quick note, I do not think we should be safeguarding against invalid data, but look into what evaluates the request as considered frontend and how oembed relates to that.
