It's been a known problem for decades, now (at least since the days of mod_perl + DBI on Apache 1.x); and AFAIK there's no data leaks from it.

Again, this is a known problem with known workarounds for decades, now. I expect nobody has been able to get close to production or dealing with important data with such a broken setup.
