Answer in brief
CVE-2026-104872 records a Medium severity (CVSS 5.8) vulnerability in Multiple @opentelemetry/instrumentation-* packages expose database username via unconditional db.user span attribute. The current sources do not mark it as known exploited. The current feed maps @opentelemetry/instrumentation-cassandra-driver (generic), @opentelemetry/instrumentation-knex (generic), @opentelemetry/instrumentation-mongoose (generic), @opentelemetry/instrumentation-mysql (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.

OpenTelemetry JavaScript Contrib provides instrumentation libraries for collecting telemetry from JavaScript applications. Prior to versions 0.66.0 of @opentelemetry/instrumentation-cassandra-driver, 0.65.0 of @opentelemetry/instrumentation-knex, 0.67.0 of @opentelemetry/instrumentation-mongoose, @opentelemetry/instrumentation-mysql, and @opentelemetry/instrumentation-mysql2, 0.46.0 of @opentelemetry/instrumentation-oracledb, 0.73.0 of @opentelemetry/instrumentation-pg, and 0.40.0 of @opentelemetry/instrumentation-tedious, the packages add the database connection username to every instrumented database operation as the db.user span attribute. The attribute is emitted by default and is not controlled by enhancedDatabaseReporting or another opt-in setting. Configured observability backends therefore receive database account names that may expose service topology, role or environment information, and account naming patterns. This issue is fixed in versions 0.66.0, 0.65.0, 0.67.0, 0.46.0, 0.73.0, and 0.40.0 of the respective packages.
