CVE-2026-81490
MongoDB Connector for BI Improper Error Handling During Schema Sampling May Cause Loss of SQL Service
CVSS Score
7.7
EPSS Score
0.0%
EPSS Percentile
0th
A database user able to create a view in a namespace that MongoDB Connector for BI samples can cause the schema-sampling routine to stop functioning by defining a view whose evaluation reliably fails. The sampling logic classifies the resulting server message as transient and, after the configured retries are exhausted, proceeds without a valid result, ending the schema refresh routine. The mongosqld process continues running without a usable schema, so SQL clients are unable to obtain results until an operator removes the view or excludes its namespace from sampling.
