CVE-2026-94384
Missing Authorization in sfExecuteAWSService Lambda Dispatcher in Amazon Connect Salesforce Lambda
Missing authorization in Amazon amazon-connect-salesforce-lambda before 5.26 allows any IAM principal with lambda:InvokeFunction permission on the affected function to escalate privileges and perform AWS API operations that their own IAM identity is explicitly denied, via invocation of a Lambda function that dispatches caller-supplied parameters to privileged service APIs without authorization validation.
To remediate this issue, we recommend upgrading to version 5.26 or later. After setup is complete, either delete or disable the sfExecuteAWSService function. If you retain the function, restrict invocation to the intended IAM user only.
