Yes. IANAL and all that, but the GPL is very clear on that, see e.g.:

In fact, library authors decidedly use the GPL (rather than the LGPL
which allows linking against proprietary software) to prevent
unsolicited use of their libraries in commercial software.

Of course, the vendor can always ask you and the author(s) of the 3rd
party library for a commercial license which allows it to distribute the
plugin with its commercial program. You can also put an exception into
your plugin license which specifically allows linking against the
commercial program, but you'd still have to ask the author(s) of the
GPL'd library for the same kind of permission.
