Adobe Analytics bug leaked customer tracking data to other tenants

Adobe reported a non-malicious ingestion bug in Adobe Analytics that from 2025-09-17 12:20 UTC to 2025-09-18 11:00 UTC caused fields from some customers' data streams to overwrite others, contaminating Analysis Workspace reports, Data Feeds, Live Stream, scheduled reports and downstream products (Customer Journey Analytics, Real-Time CDP, Journey Optimizer). Adobe reverted the change, is cleansing impacted datasets, and has advised customers to immediately purge any received data from the incident window (including backups and exports) because it may contain other customers' information; the company estimates roughly 3–5% of collected data was corrupted.
