CVE-2026-82074: MongoDB

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

MongoDB Server contains an incorrect authorization vulnerability in the aggregation framework. An authenticated user with minimal privileges can craft a specially formatted aggregation request that causes the server's authorization subsystem to evaluate a different operation than what is actually executed, resulting in unauthorized read access to collection data within the target database.

Affected products

• MongoDB MongoDB: from 7.0.0, before 7.0.41 (fixed in 7.0.41); from 8.0.0, before 8.0.30 (fixed in 8.0.30)
