Adobe is warning Analytics customers of a serious data ingestion bug that briefly mixed information between organizations, causing data from some customers to appear in others’ analytics instances.
According to Adobe’s status page, the issue began on September 17, 2025, at 12:20 UTC, when a performance optimization change introduced a flaw in Analytics Edge data collection. The bug led to “errant values” appearing in Analysis Workspace reports and affected multiple services, including Data Collection, Media Processing, Customer Attributes, and reporting tools.
Adobe reverted the change on September 18 at 11:00 UTC and stressed that the incident was not the result of malicious activity or a cyberattack. However, a private advisory seen by BleepingComputer revealed that the bug went further than Adobe’s public statement suggested, overwriting fields with values from other customers’ data streams.
The company estimates 3–5% of collected data was corrupted, with impacted rows appearing in Data Feeds, Live Stream, scheduled reports, and integrations across products like Customer Journey Analytics, Real-Time CDP, and Adobe Journey Optimizer.
The advisory instructs affected customers to immediately delete all potentially impacted data from their systems, backups, and downstream environments, since it may contain information from other organizations.
While Adobe’s policy prohibits customers from tracking personal data, consultants told BleepingComputer that many companies ignore the guidance—meaning exposed information could include email addresses, session hashes, on-site search data, and more. Experts warned the leak could raise compliance concerns under VPPA, CPPA, and GDPR, since the corrupted data may already be embedded in backups, exports, and business intelligence systems.
