Name of the Vulnerable Software and Affected Versions Dragonfly versions prior to 2.1.0

Description Dragonfly2 uses the os.MkdirAll function to create directory paths with specific access permissions. This function does not perform permission checks if a directory path already exists, allowing a local attacker to create a directory with broad permissions before Dragonfly2 does so, potentially enabling file tampering. An attacker with unprivileged access can introduce directories/paths with 0777 permissions before Dragonfly2 creates them, allowing deletion and forging of files in that directory.

Recommendations Upgrade to version 2.1.0 or later.
