EAP's Artemis deserialization configuration permits deserialization by default. ObjectMessage.getObject() uses ObjectInputStreamWithClassLoader, which implements allow-list/block-list filtering via its checkSecurity()/isTrustedType() method. However, by default both allow-list and block-list are empty. When the allow-list is empty (size == 0), isTrustedType() returns true for ALL classes. This means all classes are deserializable by default.

CVE-2026-78619.8 CRÍ—
———Deserialization of untrusted data vulnerability in Next4Biz Information Technologies Inc. CSM (Customer Service Management) allows Code Injection.
This issue affects CSM (Customer Service Management): through 07092026. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.6hCVE-2026-101969.8 CRÍ47.9%
——14The Mail Mint – Email Marketing, Newsletter, Email Automation & WooCommerce Emails plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.31.0 via deserialization of untrusted input in the 'handle_form_submission' function. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to execute code on the server. The vulnerability was partially patched in version 1.23.1.9hCVE-2026-198878.8 ALT45.2%
——14The Welcart e-Commerce plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.12.1 via deserialization of untrusted input in the Telecom EDY payment callback (usces_action_acting_transaction). Unauthenticated attackers can store arbitrary 'reserve' key/value pairs as order metadata during a public checkout, then invoke the callback with an attacker-chosen 'option' parameter to select and unserialize that metadata without any provider signature, source-address, transaction-identity or ownership check. A POP chain is present in the TCPDF library bundled with the plugin itself, so no additional plugin or theme is required. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, including wp-config.php, which can lead to remote code execution when an attacker re-runs the WordPress installer against a database they control. Successful exploitation is contingent on an admin printing an invoice to trigger file deletion.3dCVE-2026-52777—11.8%
——4YesWiki is a wiki system written in PHP. Prior to version 4.6.6, there is an authenticated PHP object injection vulnerability in BazarImportAction via unserialize. This issue has been patched in version 4.6.6.3dCVE-2026-616867.5 ALT35.1%
——11SolidInvoice is an open-source invoicing platform. Prior to version 3.0.1, the `DataGrid` LiveComponent deserializes a `context` prop value using PHP's `unserialize()` after receiving it from the client. Because the prop is marked `writable: true`, an authenticated attacker can supply an arbitrary PHP serialized payload. Version 3.0.1 fixes the issue.3dCVE-2026-197956.2 MED1.5%
——0Qiskit could allow a local attacker to cause a denial of service due to a stack overflow during deserialization of QPY payloads. A malicious QPY payload can trigger a segmentation fault, causing the application to crash when deserializing untrusted input.3d
