Adobe Analytics experienced a cross-tenant data exposure that could contaminate reports and downstream feeds with another customer's tracking data. The issue began on September 17, 2025 at 12:20 UTC after a performance optimization change introduced a bug in data collection. A private advisory said fields were overwritten with values from other customers' streams, and the affected window ran until September 18 at 11:00 UTC. Adobe said customers should delete or purge impacted data because the contamination may include information originating from other tenants.
