CVE-2020-13268Public exploitNetwork attack vector

Object-existence disclosure via unchecked import identifier

Published Jun 10, 2020 · Updated Aug 4, 2024

Information disclosure in GitLab 12.8 through 12.9.7, 12.10 through 12.10.6, and 13.0 allows remote authenticated users to test object existence. The group import API accepts a caller-supplied file.remote_id as an object-storage key, and differing error paths reveal whether that key resolves. A valid API token and group-creation access are required; the oracle confirms stored object names without returning their contents.
