CVE-2026-65921 is a high-severity path traversal vulnerability in JFrog Artifactory caused by improper path validation during archive extraction and related write handling. Archive entries containing traversal sequences can bypass the intended destination constraints and be written outside the designated build artifacts location. This weakness affects multiple self-managed Artifactory release branches prior to the vendor-fixed versions and can expose the system to unauthorized file creation or overwrite beyond the expected artifact storage boundary.
