> The fix for WW-3866 (Revision 1379386) changes the logic for acceptable 
> parameter names from
> {code:title=com.opensymphony.xwork2.interceptor.ParametersInterceptor, line 
> 282ff.}
>         boolean acceptableName = acceptableName(name)
>                  && (parameterNameAware == null || 
> parameterNameAware.acceptableParameterName(name));
> {code}
> to
> {code:title=com.opensymphony.xwork2.interceptor.ParametersInterceptor, line 
> 282ff.}
>         boolean acceptableName = acceptableName(name)
>                  || (parameterNameAware != null && 
> parameterNameAware.acceptableParameterName(name));
> {code}
> This might impose a security risk if implementations relied on their actions 
> for parameter name validation (e.g. by explicitly whitelisting parameters).
