Impact

The vulnerability is an insecure direct object reference in Julep’s get_execution_details endpoint. Authenticated tenants can supply any execution_id to read execution data belonging to other tenants, which includes task inputs, outputs, metadata and temporal task tokens. This flaw allows disclosure of sensitive execution records (CWE-639).

Affected Systems

The affected product is Julep from julep-ai. No specific version information is provided.

Risk and Exploitability

The CVSS score of 8.6 indicates high severity. The exploit requires only authenticated use of the API, a condition satisfied by any user with tenant access. The vulnerability is not listed in KEV, and the EPSS score is 0.00253 (<1%), but the high CVSS suggests that it could be leveraged for data leakage. Attackers can craft requests to the GET /executions/{execution_id} endpoint with arbitrary IDs to retrieve another tenant’s data.

OpenCVE Recommended Actions

  • Apply the latest Julep release that contains the fix for the insecure direct object reference.
  • Modify the get_execution_details access control so that it validates the requesting tenant against the data owner before returning any execution details.
  • Configure logging and monitoring to detect anomalous execution_id queries and investigate potential data leakage.
