Summary

EspoCRM before 10.0.3 lets a user with email template edit and mass email sending access reference restricted record fields in a template, because the renderer stops filtering those fields when per user ACL application is disabled. The same flaw affects group email auto replies when a regular user can edit the selected template. Rendered messages can disclose restricted user fields to a user with low privileges, with high confidentiality impact. The weakness is an authorization bypass through a user controlled key (CWE-639).

Description from the CNA

EspoCRM is an open source customer relationship management application. Prior to 10.0.3, a user with email-template edit access and mass-email sending access can reference restricted record fields in a template because the renderer stops filtering those fields when per-user ACL application is disabled. The same behavior affects group email auto-replies when a regular user can edit the selected template, even though an administrator controls the group email. Rendered messages can disclose restricted user fields. This issue is fixed in version 10.0.3.
