Adobe Analytics bug leaked customer data into other client reports

California-based software company known for its creative and marketing products, Adobe has urged its Analytics customers to immediately delete corrupted datasets after a software flaw caused some organizations’ data to appear in the reports of others for nearly 24 hours in September.

The company disclosed on its status page that the incident began on September 17, 2025, at 12:20 UTC, when a performance optimization change introduced a flaw in Adobe Analytics Edge data collection. The issue led to “errant values” being displayed in Analysis Workspace reports and disrupted several services, including Data Collection, Media Processing, Customer Attributes, and reporting tools.

Adobe said it reverted the change on September 18 at 11:00 UTC. The company confirmed the disruption was not the result of malicious activity or a cybersecurity breach but instead a coding bug that caused data streams from some customers to be overwritten with values from others.

A private advisory sent to customers and reviewed by BleepingComputer revealed that approximately 3 to 5 percent of collected data was impacted. The corrupted rows appeared in Data Feeds, Live Stream, scheduled reports, and other integrations. Because multiple Adobe products ingest Analytics data, the problem also affected Customer Journey Analytics, Real-Time CDP, and Adobe Journey Optimizer.

Adobe instructed affected customers to immediately purge all data received between September 17, 12:20 UTC, and September 18, 11:00 UTC, from their systems, backups, and downstream environments. The company warned that the corrupted data may contain field-level information from other organizations.
