No it is not a problem. As a general rule, it is good to specify
#!/bin/sh in scripts whenever this is sufficient, and to specify e.g.
#!/bin/bash only if you intend to use features that are not present in
a minimal /bin/sh. There are two reasons for this, first for portability
because any unix-like operating system will have a functioning /bin/sh
available, and second for security because feature-rich shells are more
likely to be subject to security holes, and distro maintainers take care
to link a simple and secure shell to /bin/sh.

If you are on a unix-like system and execute the command "type /bin/sh"
you will usually find it linked to something other than /usr/bin/bash.
This is because of the security concern.
