## Technical details

The vulnerability stems from insufficient enforcement of file-transfer credential direction in file-repository operations. An authenticated remote attacker with read-only access can present a download transfer credential to the upload endpoint, obtain a signed upload URL, and append chunks to files they should not be able to modify. The attack is subject to transfer size, chunk-count, and lifetime limits.
