Twenty vulnerabilities

Twenty is an open-source CRM 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 user's 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.

Twenty before 2.15.0 allows a workspace administrator with DATA_MODEL permission to supply an unescaped expression for the TS_VECTOR field, leading to SQL injection and arbitrary PostgreSQL execution as the application user.

Twenty is an open-source CRM platform. Prior to 2.22.0, field-level read permission is enforced on selected output fields but not on GraphQL or REST filter predicates. A workspace member or API key with permission to read an object but not a particular field can reference that denied field in direct filters, relation filters, or persisted view filters. The resulting totalCount and row presence reveal whether guesses match the real column, forming a boolean/count oracle that can reconstruct denied field values for records exposed by the principal's row-level policy.

Twenty before 2.35.0 fails to validate field and row permissions in the groupBy-with-records GraphQL resolver, allowing authenticated users to bypass permission checks. Attackers with canReadObjectRecords permission but canReadFieldValue false can retrieve restricted field values through the groupBy resolver that would normally be denied.

Twenty through 2.35.0 contains an open redirect vulnerability in the OAuthPropagatorController.propagateOAuthCallback endpoint that treats the state query parameter as a redirect URL. Attackers can craft malicious requests to redirect users to arbitrary hosts while forwarding OAuth authorization codes, bypassing domain validation when IS_MULTIWORKSPACE_ENABLED is disabled.

Twenty (open source CRM) versions 1.18.0 and earlier have an SSRF vulnerability where protection in SecureHttpClientService can be bypassed using IPv4-mapped IPv6 addresses in URL IP literals. Node.js normalizes such addresses to compressed hex form, but the isPrivateIp function only recognizes dotted-decimal notation.
