Details
As written in the advisory (Markdown source, shown as plain text).
### 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` |
| `@opentelemetry/instrumentation-pg` | `< 0.73.0` | `0.73.0` |
| `@opentelemetry/instrumentation-tedious` | `< 0.40.0` | `0.40.0` |
### Patches
Fixed in the coordinated release on 2026-07-23 via
[feat!: only emit stable http, network and database attributes (#3585)](https://github.com/open-telemetry/opentelemetry-js-contrib/pull/3585).
Upgrade to the patched version listed in the table above for each instrumentation package in use.
### Workarounds
No configuration-level workaround exists in the affected versions: the `db.user` attribute cannot be
suppressed without patching. As a partial mitigation, a custom `SpanProcessor` can be used to strip `db.user` from spans before they leave the process:
```ts
// Example: drop db.user in a custom SpanProcessor
class StripDbUserProcessor implements SpanProcessor {
onStart(span: Span) {
span.setAttribute('db.user', null);
}
onEnd() {}
shutdown() { return Promise.resolve(); }
forceFlush() { return Promise.resolve(); }
}
```
Users who control the downstream collector can also filter the attribute at the collector pipeline level.
