XWiki Platform users may execute anything with superadmin right through comments and async macro
Impact
Comments are supposed to be executed with the right of superadmin but in restricted mode (anything dangerous is disabled) but the async macro is not taking into account the restricted mode.
This means that any user with comment right can use the async macro to make it execute any wiki content with the right of superadmin as in:
{{async}} {{groovy}}println "it works !"{{/groovy}} {{/async}}
Patches
This has been patched in XWiki 14.9, 14.4.6, and 13.10.10.
Workarounds
The only known workaround consists in applying the following patch and rebuilding and redeploying org.xwiki.platform:xwiki-platform-rendering-async-macro.
