Improper Link Resolution Before File Access ('Link Following')
Directory traversal vulnerability in the WordPress Download Manager plugin for WordPress allows remote attackers to read arbitrary files via a .. (dot dot) in the fname parameter to (1) views/file_download.php or (2) file_download.php.
CWE-59 - Improper Link Resolution Before File Access
'Improper link resolution before file access' occurs when software accesses a file resource but fails to verify that the file isn't a link or shortcut to another file. An attacker can potentially gain access to arbitrary files and from there the impact can vary, depending on the application, from sensitive data exposure to remote code execution.
