AnalysisAIv1 – Sep 16, 2026

An authenticated user of IBM DataStage on Cloud Pak for Data 5.4.0.0 can abuse path traversal (CWE-22) in file path handling to write to or delete arbitrary files on the platform's shared storage, compromising data integrity and availability for other jobs and tenants using that storage. The flaw is remotely reachable with a valid low-privileged account (CVSS 8.1, AV:N/PR:L, C:N/I:H/A:H) and a vendor patch is available from IBM; there is no CISA KEV listing and no confirmed public exploit, and EPSS is a modest 0.50% (41st percentile), indicating opportunistic rather than widespread exploitation pressure.

What every action level means
Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.
Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.
This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.
This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.
Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
