Multiple @opentelemetry/instrumentation-* packages expose database username via unconditional db.user span attribute

Type: advisorySource: OSV1 source record

### Impact Multiple `@opentelemetry/instrumentation-*` packages recorded the database connection username as the `db.user` span attribute on every instrumented database operation. This attribute was emitted unconditionally — it was not gated by `enhancedDatabaseReporting` or any other opt-in flag, and it was the **default** behaviour for all users of the affected packages until the patched releases shipped on 2026-07-23. The attribute is forwarded to every configured observability backend (Jaeger, Zipkin, Datadog, OTLP collectors, etc.). Depending on the database account naming convention in use, the exported value may reveal: - Internal service account names that disclose architecture topology. - Role-encoded usernames (e.g. `admin_readwrite`, `app_readonly_prod`) useful for privilege inference. - Database account naming patterns useful for credential enumeration. Affected packages (all are vulnerable from the first published version through the version listed below): | Package | Vulnerable range | Patched version | |---------|-----------------|-----------------| | `@opentelemetry/instrumentation-cassandra-driver` | `< 0.66.0` | `0.66.0` | | `@opentelemetry/instrumentation-knex` | `< 0.65.0` | `0.65.0` | | `@opentelemetry/instrumentation-mongoose` | `< 0.67.0` | `0.67.0` | | `@opentelemetry/instrumentation-mysql` | `< 0.67.0` | `0.67.0` | | `@opentelemetry/instrumentation-mysql2` | `< 0.67.0` | `0.67.0` | | `@opentelemetry/instrumentation-oracledb` | `< 0.46.0` | `0.46.0` |
