That varies from brand to brand, but generally, yes. Given that it's happened to devices whose manufacturers have a long history of being part of large enterprise security mechanisms, flaws are still being found and actively exploited.
While this isn't an indicator of the quality of newer brands specifically, I believe it's reflective of the state of the industry as a whole -- in that digital physical security as a whole is still immature and shouldn't be trusted to keep bad guys (determined adversaries) at bad.
