Overview

AI description

Automated description summarized from trusted sources.

CVE-2026-66384 is identified as a path traversal vulnerability (CWE-22) affecting JFrog Artifactory. This flaw allows an authenticated user to write data outside of the designated Docker cache path. This can occur when specific remote-repository conditions are met within the Artifactory environment. The vulnerability stems from how JFrog Artifactory handles path construction for cached Docker artifacts retrieved through remote repositories. Under certain configurations, the input used to determine the cache path is not adequately normalized against traversal sequences, enabling an authenticated user with appropriate permissions to manipulate the write path. This results in files being written to arbitrary locations accessible by the Artifactory process, thereby undermining the integrity of files on the Artifactory server.

Description: An authenticated user may write data outside the intended Docker cache path under specific remote-repository conditions.
