This is a path traversal vulnerability when Gradle deals with Tar archives, often referenced as TarSlip, a variant of ZipSlip. When unpacking Tar archives, Gradle did not check that files could be written outside of the unpack location, which could lead to important files being overwritten anywhere the Gradle process has write permissions. For a build reading Tar entries from a Tar archive, this issue could allow Gradle to disclose information from sensitive files through an arbitrary file read. To exploit this behavior, an attacker needs to either control the source of an archive already used by the build or modify the build to interact with a malicious archive. Gradle uses Tar archives for its Build Cache, and if an attacker had control of a remote build cache server, they could inject malicious build cache entries that leverage this vulnerability.
