Subtle bugs that result in security vulnerabilities tug at our emotions. They evoke the very reasons many of us were drawn to security in the first place. It's that exhilarating sensation of thinking beyond the ordinary, of delving into those overlooked details that many might miss. The allure lies in understanding and feeling the intricacies, reminding us of the depth and humanity behind every line of code. However, they also serve as humbling reminders of our fallibility — that things can still go awry no matter how careful we are.
In this post, I'll discuss a bug pattern I've detected across multiple projects recently, which isn’t really new. The recent vulnerability advisories and CVEs should be out soon. Given its subtleness, it has stayed hidden, lurking in the shadows for so long. As security professionals, we must shed light on these overlooked bugs. Only through diligent documentation and shared knowledge can we hope to eradicate them.
