Title

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

Summary

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.

Vulnerability from github – Published: 2026-10-05 22:52 – Updated: 2026-10-05 22:52

Summary

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

Details

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).

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:

// 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.

Severity

5.8 (Medium)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
