  "summary" : "Multiple @opentelemetry/instrumentation-* packages expose database username via unconditional db.user span attribute",
  "details" : "### Impact\n\nMultiple `@opentelemetry/instrumentation-*` packages recorded the database connection username as the `db.user`\nspan attribute on every instrumented database operation. This attribute was emitted unconditionally — it was\nnot gated by `enhancedDatabaseReporting` or any other opt-in flag, and it was the **default** behaviour for\nall users of the affected packages until the patched releases shipped on 2026-07-23.\n\nThe attribute is forwarded to every configured observability backend (Jaeger, Zipkin, Datadog, OTLP\ncollectors, etc.).  Depending on the database account naming convention in use, the exported value may\nreveal:\n\n- Internal service account names that disclose architecture topology.\n- Role-encoded usernames (e.g. `admin_readwrite`, `app_readonly_prod`) useful for privilege inference.\n- Database account naming patterns useful for credential enumeration.\n\nAffected packages (all are vulnerable from the first published version through the version listed below):\n\n| Package | Vulnerable range | Patched version |\n|---------|-----------------|-----------------|\n| `@opentelemetry/instrumentation-cassandra-driver` | `< 0.66.0` | `0.66.0` |\n| `@opentelemetry/instrumentation-knex`             | `< 0.65.0` | `0.65.0` |\n| `@opentelemetry/instrumentation-mongoose`         | `< 0.67.0` | `0.67.0` |\n| `@opentelemetry/instrumentation-mysql`            | `< 0.67.0` | `0.67.0` |\n| `@opentelemetry/instrumentation-mysql2`           | `< 0.67.0` | `0.67.0` |\n| `@opentelemetry/instrumentation-oracledb`         | `< 0.46.0` | `0.46.0` |\n| `@opentelemetry/instrumentation-pg`               | `< 0.73.0` | `0.73.0` |\n| `@opentelemetry/instrumentation-tedious`          | `< 0.40.0` | `0.40.0` |\n\n### Patches\n\nFixed in the coordinated release on 2026-07-23 via\n[feat!: only emit stable http, network and database attributes (#3585)](https://github.com/open-telemetry/opentelemetry-js-contrib/pull/3585).\n\nUpgrade to the patched version listed in the table above for each instrumentation package in use.\n\n### Workarounds\n\nNo configuration-level workaround exists in the affected versions: the `db.user` attribute cannot be\nsuppressed without patching. As a partial mitigation, a custom `SpanProcessor` can be used to strip `db.user` from spans before they leave the process:\n\n```ts\n// Example: drop db.user in a custom SpanProcessor\nclass StripDbUserProcessor implements SpanProcessor {\n  onStart(span: Span) {\n    span.setAttribute('db.user', null);\n  }\n  onEnd() {}\n  shutdown() { return Promise.resolve(); }\n  forceFlush() { return Promise.resolve(); }\n}\n```\n\nUsers who control the downstream collector can also filter the attribute at the collector pipeline level.",
