CVE-2026-41141Public exploitNetwork attack vector

Entity data disclosure via unchecked email lookup

Published May 28, 2026 · Updated May 28, 2026

Authorization bypass in EspoCRM before 9.3.5 allows remote authenticated users to read CRM entity fields through email template preparation. Processor::prepare() resolves a supplied email address to a Contact, Lead, Account, or User and adds the entity to the rendering context without checking read ACLs. EmailTemplate read permission and the target's email address are sufficient to substitute restricted fields into the API response, bypassing own- or team-scoped access.
