Please provide a reproducer (and ideally one that is built with only the library, not a Laravel app where the usage of the library is hidden in tens of abstraction levels).

[stof]

And can you tell which exact version of PHP you are using ? This might be a bug in ext-dom.

[arifurrahmansw]

Thanks for the quick response. PHP 8.1

[stof]

that's not the exact version.

[arifurrahmansw]

PHP 8.1.0 and Laravel Framework 8.83.27

[arifurrahmansw]

when I upgrade laravel 6 to laravel 8 showing this error.

Please upgrade to the latest 8.1.x release to see whether it fixes the issue. PHP has fixed many issues between 8.1.0 and 8.1.14

I am having the same problem, my setup includes:

• php: 8.1.17
• tijsverkoyen/css-to-inline-styles: 2.2.6
• laravel/framework: 9.52.7

PHP has fixed many issues between 8.1.0 and 8.1.14

What changes of php are releated to this package? Only changes related to DomDocument were last referred to in Version 8.1.11.

DOM:
Fixed bug #66783 (UAF when appending DOMDocument to element).

Please try to build a standalone reproducer for this issue. Otherwise, there is nothing I can do to debug the issue.

Yeah, sorry, I thought you might be able to suggest a possible problem off the top of your head, since you mentioned issues related to the package based on php's versions. I believe it'd be really hard to create a standalone reproducer of the issue, because as you said in Laravel "usage of the library is hidden in tens of abstraction levels".

Thank you for your time!

Well, some of the PHP 8.1.x releases fixed issues related to typed properties in internal classes. But I'm not sure whether this is before or after 8.1.11.

I updated my servers php version to 8.2.4 and the issue is no longer there. I also noticed that there's a new 8.1.x version, but I didn't bother checking out before upgrading straight to 8.2. Leaving that here, hope it helps someone.
