@nicolas-grekas asked me to to have a look at this after #36678.
If a user has a CSP policy of
default-src 'none'
, then the WebProfiler copies'none'
toscript-src
andstyle-src
then adds other sources. This creates an invalid policy since'none'
is only allowed when it's the only item in the source list.This will probably need to be merged into 3.4 first, I started on 4.4 so I can test in my current symfony project which requires 4.4.
