Andreas Sachs commented on WW-5504:
-----------------------------------
I think of two possibilities:
* only set a nonce if there isn't a nonce in the session (maybe not a good
idea with long living sessions)
* use request attributes instead of session attributes
A already tried the second one (changes in DefaultCspSettings and UIBean): i
had to change my own component from session to request attributes, but it
worked, as far as i can see.
> CSP Nonce changes within a page
> -------------------------------

> Key: WW-5504
> URL: https://issues.apache.org/jira/browse/WW-5504
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors
> Affects Versions: 6.7.0
> Reporter: Andreas Sachs
> Priority: Major
> Fix For: 6.7.1
>
>
> Sometimes the CSP nonce changes within a page.
>
> <script type="text/javascript" src="..." nonce="A"> </script>
> <script type="text/javascript" src="..." nonce="A"> </script>
> ...
> <script type="text/javascript" src="..." nonce="B"> </script>
>
> This happens if there are concurrent requests within the same session.
>
> Each request stores a new nonce in the session:
>
> DefaultCspSettings:
> request.getSession().setAttribute("nonce", nonceValue);
>
> If the first request is not finished, the second request will change the
> nonce of the first request.
