CVE-2026-76576

Name of the Vulnerable Software and Affected Versions yangzongzhuan RuoYi-Vue versions prior to 3.9.3

Description A path traversal issue exists in the Common Download Endpoint within the fileDownload() and resourceDownload() functions of the CommonController.java file. A remote attacker can manipulate the fileName or resource arguments to access files outside the intended directory. Path traversal is a technique used to access files and directories that are stored outside the web root folder by manipulating variables that reference files with dot-dot-slash (../) sequences.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, restrict access to the fileDownload() and resourceDownload() functions to minimize the risk of exploitation.
