Onedev

OneDev is a Git server with CI/CD, kanban, and packages. In versions 15.0.6 and below, TarUtils.untar() creates symbolic links verbatim from TAR entry getLinkName() without validating whether the target is an absolute path. A subsequent file entry in the same archive traverses the symlink, writing to arbitrary server-side locations. This is exploitable by any authenticated user with CI Job write access — no admin interaction required. This is an incomplete fix bypass of CVE-2021-21251 (GHSA-2w6j-wc8c-9mq2): that patch blocked .. path segments but did not address absolute symlink targets. This issue has been fixed in version 15.0.7.

OneDev is a Git server with CI/CD, kanban, and packages. Prior to 15.0.2, there is behavior that breaks the expected boundary between repository-controlled LFS metadata and server-local filesystem paths. A repository object can steer raw blob reads to arbitrary local files that the server account can access. User with push permission to any repository will be able to access any server files accessible by server process. This vulnerability is fixed in 15.0.2.
