Twenty is an open-source CRM (customer relationship management) platform. From 1.20.10 until 2.7.0, the /metadata GraphQL connectedAccounts query returned connectionParameters from ConnectedAccountDTO for every connected account in a workspace, including plaintext IMAP, SMTP, and CalDAV passwords, because the field was not hidden and the lookup did not enforce the calling users identity or account visibility. A normal workspace member could obtain other members external-service credentials and use them to access mail or calendars and potentially reset third-party accounts. Google and Microsoft OAuth-only workspaces were not affected. This issue is fixed in version 2.7.0.
Weakness
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
