In simple terms, an unqualified library call is when a program doesn&#8217;t specify the library that is to be used for a certain function. This can lead to the wrong library being called and manipulated, especially if a malicious <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2023-47294-critical-vulnerability-in-ncr-terminal-handler-v1-5-1-allows-user-account-manipulation\/\"  data-wpil-monitor-id=\"63758\">user is aware of this vulnerability<\/a>. In this case, the malicious user can insert their own library into the library list, which would then be called instead of the intended library.
