CVE-2017-12149Cri0.929.80.94KEVOct 4, 2017In Jboss Application Server as shipped with Red Hat Enterprise Application Platform 5.2, it was found that the doFilter method in the ReadOnlyAccessFilter of the HTTP Invoker does not restrict classes for which it performs deserialization and thus allowing an attacker to execute arbitrary code via crafted serialized data.
CVE-2017-3066Cri0.869.80.94KEVApr 27, 2017Adobe ColdFusion 2016 Update 3 and earlier, ColdFusion 11 update 11 and earlier, ColdFusion 10 Update 22 and earlier have a Java deserialization vulnerability in the Apache BlazeDS library. Successful exploitation could lead to arbitrary code execution.
CVE-2015-7450Cri0.869.80.93KEVJan 2, 2016Serialized-object interfaces in certain IBM analytics, business solutions, cognitive, IT infrastructure, and mobile and social products allow remote attackers to execute arbitrary commands via a crafted serialized Java object, related to the InvokerTransformer class in the Apache Commons Collections library.
CVE-2015-4852Cri0.869.80.93KEVNov 18, 2015The WLS Security component in Oracle WebLogic Server 10.3.6.0, 12.1.2.0, 12.1.3.0, and 12.2.1.0 allows remote attackers to execute arbitrary commands via a crafted serialized Java object in T3 protocol traffic to TCP port 7001, related to oracle_common/modules/com.bea.core.apache.commons.collections.jar. NOTE: the scope of this CVE is limited to the WebLogic Server product.

CVE-2026-20963Cri0.769.80.05KEVJan 13, 2026Deserialization of untrusted data in Microsoft Office SharePoint allows an unauthorized attacker to execute code over a network.
CVE-2024-8353Cri0.749.80.92Sep 28, 2024The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.16.1 via deserialization of untrusted input via several parameters like 'give_title' and 'card_address'. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to delete arbitrary files and achieve remote code execution. This is essentially the same vulnerability as CVE-2024-5932, however, it was discovered the the presence of stripslashes_deep on user_info allows the is_serialized check to be bypassed. This issue was mostly patched in 3.16.1, but further hardening was added in 3.16.2.
CVE-2024-55556Cri0.739.80.85Jan 7, 2025A vulnerability in Crater Invoice allows an unauthenticated attacker with knowledge of the APP_KEY to achieve remote command execution on the server by manipulating the laravel_session cookie, exploiting arbitrary deserialization through the encrypted session data. The exploitation vector of this vulnerability relies on an attacker obtaining Laravel's secret APP_KEY, which would allow them to decrypt and manipulate session cookies (laravel_session) containing serialized data. By altering this data and re-encrypting it with the APP_KEY, the attacker could trigger arbitrary deserialization on the server, potentially leading to remote command execution (RCE). The vulnerability is primarily exploited by accessing an exposed cookie and manipulating it using the secret key to gain malicious access to the server.
CVE-2012-0911Cri0.739.80.78Jul 12, 2012TikiWiki CMS/Groupware before 6.7 LTS and before 8.4 allows remote attackers to execute arbitrary PHP code via a crafted serialized object in the (1) cookieName to lib/banners/bannerlib.php; (2) printpages or (3) printstructures parameter to (a) tiki-print_multi_pages.php or (b) tiki-print_pages.php; or (4) sendpages, (5) sendstructures, or (6) sendarticles parameter to tiki-send_objects.php, which is not properly handled when processed by the unserialize function.
CVE-2024-52433Cri0.709.80.80Nov 18, 2024Deserialization of Untrusted Data vulnerability in Mindstien Technologies My Geo Posts Free my-geo-posts-free allows Object Injection.This issue affects My Geo Posts Free: from n/a through <= 1.2.
CVE-2016-15044Cri0.69—0.67Jul 23, 2025A remote code execution vulnerability exists in Kaltura versions prior to 11.1.0-2 due to unsafe deserialization of user-controlled data within the keditorservices module. An unauthenticated remote attacker can exploit this issue by sending a specially crafted serialized PHP object in the kdata GET parameter to the redirectWidgetCmd endpoint. Successful exploitation leads to execution of arbitrary PHP code in the context of the web server process.
CVE-2025-25034Cri0.69—0.71Jun 20, 2025A PHP object injection vulnerability exists in SugarCRM versions prior to 6.5.24, 6.7.13, 7.5.2.5, 7.6.2.2, and 7.7.1.0 due to improper validation of PHP serialized input in the SugarRestSerialize.php script. The vulnerable code fails to sanitize the rest_data parameter before passing it to the unserialize() function. This allows an unauthenticated attacker to submit crafted serialized data containing malicious object declarations, resulting in arbitrary code execution within the application context. Although SugarCRM released a prior fix in advisory sugarcrm-sa-2016-001, the patch was incomplete and failed to address some vectors. Exploitation evidence was observed by the Shadowserver Foundation on 2024-09-13 UTC.
CVE-2013-1465Cri0.699.80.31Feb 8, 2013The Cubecart::_basket method in classes/cubecart.class.php in CubeCart 5.0.0 through 5.2.0 allows remote attackers to unserialize arbitrary PHP objects via a crafted shipping parameter, as demonstrated by modifying the application configuration using the Config object.
CVE-2017-9805Hig0.688.10.94KEVSep 15, 2017The REST Plugin in Apache Struts 2.1.1 through 2.3.x before 2.3.34 and 2.5.x before 2.5.13 uses an XStreamHandler with an instance of XStream for deserialization without any type filtering, which can lead to Remote Code Execution when deserializing XML payloads.
CVE-2025-62368Cri0.679.00.64Oct 28, 2025Taiga is an open source project management platform. In versions 6.8.3 and earlier, a remote code execution vulnerability exists in the Taiga API due to unsafe deserialization of untrusted data. This issue is fixed in version 6.9.0.
CVE-2024-56058Cri0.679.80.44Dec 18, 2024Deserialization of Untrusted Data vulnerability in denniskravetstns VRPConnector vrpconnector allows Object Injection.This issue affects VRPConnector: from n/a through <= 2.0.1.
CVE-2025-34067Cri0.66—0.08Jul 2, 2025An unauthenticated remote command execution vulnerability exists in the applyCT component of the Hikvision Integrated Security Management Platform due to the use of a vulnerable version of the Fastjson library. The endpoint /bic/ssoService/v1/applyCT deserializes untrusted user input, allowing an attacker to trigger Fastjson's auto-type feature to load arbitrary Java classes. By referencing a malicious class via an LDAP URL, an attacker can achieve remote code execution on the underlying system. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-05 UTC.
