CVE-2026-75505

EspoCRM: Access control bypass in Mass Update letting regular user with Mass Update permission read any attachment

Published Oct 15, 2026 CVSS 4.0 · 6 Medium EPSS < 1% KEV · Not listed
Description
EspoCRM is an open source customer relationship management application. Prior to 10.0.2, an authenticated user with mass-update permission can supply a known attachment identifier to the mass-update functionality. The mass-update processor duplicates the attachment without checking whether the caller can read it, bypassing record-level and field-level restrictions and exposing the file contents through the copied attachment. Obtaining a valid attachment identifier may be difficult. This issue is fixed in version 10.0.2.
