In light of recent events: the PHP security vulnerabilities that have been making headlines since yesterday do not affect dexters-web.de or the OVMS services I host.
My web applications are not based on PHP; instead, they rely on "expeedo," a system I developed myself. This is a fundamental component of the security strategy for my e-commerce web services.
However, if you use other solutions based on PHP, you should take action immediately. You can find further information and guidance on this online.
