CVE-2026-81554

IBM DataStage on Cloud Pak for Data 5.4.0.0 allows a remote authenticated attacker to execute arbitrary OS commands. The cause is improper neutralization of special elements used in OS commands.

IBM DataStage on Cloud Pak for Data 5.4.0.0 allows a remote authenticated attacker to execute arbitrary code due to a Server-Side Request Forgery (SSRF) vulnerability. The application makes requests to attacker-controlled resources.

IBM DataStage on Cloud Pak for Data 5.4.0.0 allows a remote authenticated attacker to execute arbitrary code due to improper neutralization of special elements used in OS commands. The flaw enables command injection into the operating system.

IBM DataStage on Cloud Pak for Data 5.4.0.0 allows a remote authenticated attacker to obtain sensitive information due to an absolute-path traversal vulnerability. The attacker can read files outside the permitted directory.

IBM DataStage on Cloud Pak for Data 5.4.0.0 allows a remote authenticated attacker to arbitrarily write to or delete files on shared storage due to a path traversal vulnerability. The attacker can manipulate files outside the permitted area.

IBM DataStage on Cloud Pak for Data 5.4.0.0 allows a remote authenticated attacker to execute arbitrary code due to improper neutralization of special elements used in OS commands. The flaw enables command injection into the operating system.

IBM DataStage on Cloud Pak for Data 5.4.0.0 allows a remote authenticated attacker to overwrite ruleset files belonging to other tenants due to a path traversal vulnerability. The attacker can modify files outside their own area.

IBM DataStage on Cloud Pak for Data 5.4.0.0 concatenates three caller-supplied strings into a String.format path on the shared /ds-storage RWX PVC and returns the file with no project ACL — pure IDOR plus traversal. Read is constrained to files named job.log/error.log, but DataStage job logs routinely carry connection strings, {dsnextenc} ciphertexts, and customer-data row samples.

IBM DataStage on Cloud Pak for Data 5.4.0.0 allows any authenticated tenant — with no project membership or role — fully controls scheme/host/port/path of an outbound fetch originating from a shared-infrastructure pod, and the WSDL body is reflected verbatim to the caller. The ds-canvas pod sits on the OpenShift overlay with reach to co-tenant services, in-cluster CP4D APIs, and link-local addresses.

IBM DataStage on Cloud Pak for Data 5.4.0.0 could allow a remote authenticated attacker to cause a denial of service by deleting arbitrary RabbitMQ queues or exchanges due to improper authorization.
