CVE-2026-33656
CriticalSummary
EspoCRM to aplikacja do zarządzania relacjami z klientami, która przed wersją 9.3.4 miała wbudowany silnik skryptów umożliwiający aktualizację pola `sourceId` w encjach `Attachment`. Dzięki temu uwierzytelniony administrator mógł nadpisać to pole, co prowadziło do potencjalnego przekierowania operacji odczytu lub zapisu plików do dowolnej lokalizacji w obrębie serwera.
Risk Assessment
Atakujący mógł wykorzystać tę podatność do manipulacji ścieżkami plików, co stwarzało ryzyko nieautoryzowanego dostępu do danych lub ich modyfikacji. To może prowadzić do poważnych naruszeń bezpieczeństwa w organizacji.
Recommendation
Zaleca się aktualizację EspoCRM do wersji 9.3.4 lub nowszej, aby usunąć tę podatność. Dodatkowo warto przeprowadzić audyt bezpieczeństwa aplikacji oraz monitorować logi w celu wykrycia potencjalnych prób wykorzystania tej luki.

Original NVD description (English source)
EspoCRM is an open source customer relationship management application. Prior to version 9.3.4, EspoCRM's built-in formula scripting engine allowing updating attachment's sourceId thus allowing an authenticated admin to overwrite the `sourceId` field on `Attachment` entities. Because `sourceId` is concatenated directly into a file path with no sanitization in `EspoUploadDir::getFilePath()`, an attacker can redirect any file read or write operation to an arbitrary path within the web server's `open_basedir` scope. Version 9.3.4 fixes the issue.
