CVE-2026-39822

Name of the Vulnerable Software and Affected Versions The product name cannot be determined (affected versions not specified)

Description On Unix systems, opening a file in an os.Root improperly follows symbolic links to locations outside of the Root. This occurs when the final path component of a path is a symbolic link and the path ends in a forward slash (/). For instance, calling root.Open("symlink/") allows access to the target of the symbolic link even if it points outside the designated root directory.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
