CVE-2026-47168 Details
Description
EspoCRM is an open source customer relationship management application. Prior to 9.3.7, an authenticated administrator can supply crafted serialized PHP object data that is stored in background MassAction or Export parameters and later deserialized by the application. The deserialization paths do not restrict allowed classes, allowing attacker-controlled object instantiation and arbitrary code execution on the server. This issue is fixed in version 9.3.7.
A remote code execution vulnerability has been identified in EspoCRM versions prior to 9.3.7. This issue arises from insecure deserialization of PHP objects in the background MassAction and Export parameters. An authenticated administrator can exploit this vulnerability by sending crafted serialized data that is stored and later deserialized by the application. The deserialization process does not restrict the classes that can be instantiated, allowing for attacker-controlled object creation and execution of arbitrary code on the server.
Users can upgrade to EspoCRM version 9.3.7 or later to address this vulnerability.
