OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.12 and earlier, when the AuthType is set to anything but Basic, if the request contains an Authorization: Basic ... header, the password is not checked. This results in authentication bypass. Any configuration that allows an AuthType that is not Basic is affected. Version 2.4.13 fixes the issue.
