CVE-2023-39438Network attack vector

Authenticated data access via incomplete route allowlist

Published Aug 15, 2023 · Updated Oct 8, 2024

Missing authorization in SAP SE CLA Assistant 2.13.0 and earlier allows remote authenticated users to read and alter CLA data. The API's authenticated-route allowlist admits signed-in users to sensitive operations without repository or organization authorization checks. Any authenticated account can expose signer data and custom fields or update and delete CLA configurations; stored GitHub access tokens remain redacted.
