Twenty vulnerabilities

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 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.
