Technical details
This vulnerability exists in the AWS AgentCore Python SDK's OpenTelemetry span instrumentation, where sensitive information such as API keys, credentials, or confidential request/response data is not properly sanitized before being recorded in telemetry spans. The root cause is inadequate data filtering or redaction in the span collection and export pipeline. An attacker with access to observability systems (logs, traces, metrics), monitoring dashboards, or telemetry backends could retrieve this exposed sensitive data. The vulnerability does not require authentication or user interaction—any agent application using the affected SDK versions will automatically expose data through normal operation. AWS has published a security bulletin and likely provided patched versions of the SDK; users should update to the latest version to remediate this issue.
