CVE-2026-25030 is a vulnerability in the park_of_ideas Goldish product caused by unsafe deserialization of untrusted data, leading to object injection attacks. Deserialization vulnerabilities occur when applications deserialize data from untrusted sources without proper validation, allowing attackers to manipulate serialized objects to execute arbitrary code or alter program flow. In Goldish versions prior to 3.47, this flaw enables attackers to inject malicious objects during the deserialization process. The vulnerability arises because the application does not adequately verify or sanitize serialized input before deserializing it, exposing it to object injection attacks. Such attacks can lead to remote code execution, privilege escalation, data tampering, or denial of service. No CVSS score has been assigned yet, and no patches or official mitigations have been released. The vulnerability was reserved in January 2026 and published in March 2026. Although no active exploits are reported, the nature of deserialization vulnerabilities makes them attractive targets for attackers. Organizations running vulnerable versions of Goldish should consider this a critical security risk and prepare to apply patches once available or implement interim mitigations.

The impact of this vulnerability on organizations worldwide can be severe. Exploitation could allow attackers to execute arbitrary code remotely, leading to full system compromise, data breaches, or service disruption. Confidentiality could be compromised through unauthorized data access or exfiltration. Integrity could be affected by unauthorized modification of data or application behavior. Availability might be impacted if attackers cause crashes or denial of service. Because Goldish is a product used in certain sectors, organizations relying on it for critical operations could face operational downtime and reputational damage. The absence of known exploits currently reduces immediate risk, but the potential for rapid weaponization remains high once exploit code is developed. Organizations without timely patching or mitigation strategies could be vulnerable to targeted attacks, especially in environments exposed to untrusted input sources.

1. Immediately inventory and identify all instances of Goldish in your environment and verify their versions. 2. Restrict or block untrusted input sources that could send serialized data to Goldish applications, using network segmentation and input validation controls. 3. Implement application-layer filtering or web application firewalls (WAFs) to detect and block suspicious serialized payloads or object injection attempts. 4. Monitor logs and network traffic for anomalous deserialization activity or unexpected serialized data patterns. 5. Engage with the vendor (park_of_ideas) for updates and patches; apply official patches promptly once released. 6. If patching is delayed, consider disabling or restricting features that process serialized data from untrusted sources. 7. Conduct code reviews and security testing focusing on deserialization processes to identify and remediate unsafe deserialization. 8. Educate developers and administrators about the risks of deserialization vulnerabilities and secure coding practices. 9. Employ runtime application self-protection (RASP) or endpoint detection and response (EDR) tools to detect exploitation attempts. 10. Prepare incident response plans specifically addressing exploitation of deserialization vulnerabilities.
