Description
The following is part of the default Page Layout in Confluence:
#applyDecorator("root") #decoratorParam("sitemeshPage" $sitemeshPage) #decoratorParam("page" $page) #decoratorParam("context" "comments") #end
If "#decoratorParam("context" "comments")" is taken out by editing the layout, accessing a page affected by this will cause Confluence to run out of memory. This can happen even if the custom layout is applied at a space level, meaning space admins can take down Confluence accidentally.
The stack trace:
