CVE-2026-41141 Details
Description
EspoCRM is an open source customer relationship management application. Prior to 9.3.5, the POST /api/v1/EmailTemplate/:id/prepare endpoint accepts an emailAddress parameter and resolves the owning entity (Contact, Lead, Account, or User) without performing an ACL check. An authenticated user with EmailTemplate read permission can extract all field values of any entity by supplying the target's email address, bypassing read: own or read: team ACL restrictions. This vulnerability is fixed in 9.3.5.
A vulnerability exists in EspoCRM versions prior to 9.3.5 within the POST /api/v1/EmailTemplate/:id/prepare endpoint. The endpoint accepts an emailAddress parameter and resolves the associated entity (Contact, Lead, Account, or User) without conducting an ACL check. This flaw enables an authenticated user with EmailTemplate read permission to access all field values of any entity by providing the target's email address, thereby circumventing read: own or read: team ACL restrictions. The issue arises because, when entities are resolved by email address, the process bypasses necessary access controls, directly adding the entity to the template rendering context and exposing all referenced data in the API response.
Users are advised to update EspoCRM to version 9.3.5 or later, where this vulnerability has been fixed.
