The relative_path_validator function only verifies that content paths do not begin with \"/\" but fails to block directory traversal sequences such as \"../\" anywhere in the path. An authenticated administrator can craft a relative_path containing embedded traversal sequences (e.g., \"looking/normal/../../../../etc/shadow\") that escapes the intended export directory during FilesystemExport operations. Because the file content is also user-controlled (uploaded artifact), this allows arbitrary file write to any location writable by the Pulp service user, potentially leading to service compromise or further system exploitation.","Type":"Description","Title":"Pulpcore: pulpcore: relative_path_validator bypass via directory"}]}}}
