CVE-2025-61810: 
Adobe ColdFusion vulnerability analysis and mitigation

CVE-2025-61810 is a Deserialization of Untrusted Data vulnerability (CWE-502) in Adobe ColdFusion that allows a high-privileged attacker to execute arbitrary code in the context of the current user by supplying maliciously crafted serialized data. It affects ColdFusion versions 2021 (through Update 22), 2023 (through Update 16), and 2025 (through Update 4). The vulnerability was disclosed on December 9, 2025, and published to NVD on December 10, 2025. It carries a CVSS v3.1 base score of 8.4 (High), assigned by Adobe (Adobe Advisory).

The root cause is improper deserialization of untrusted data (CWE-502), classified under CAPEC-586 (Object Injection). An attacker with high privileges can craft a malicious serialized payload and submit it to the ColdFusion application, triggering arbitrary code execution during the deserialization process. Exploitation requires both high privileges and user interaction (e.g., an administrator processing or importing attacker-controlled data), and the scope is changed, meaning the impact can extend beyond the vulnerable component itself. No public proof-of-concept or detailed technical write-up has been identified at this time (Adobe Advisory).

Successful exploitation results in arbitrary code execution in the context of the current user, with high impact to confidentiality, integrity, and availability of the affected ColdFusion instance. An attacker could fully compromise the application server, access sensitive data, modify or destroy application data, and potentially pivot to other systems on the network. The changed scope indicator means the impact may extend beyond the ColdFusion process itself to other components or systems (Adobe Advisory).

Adobe has released patches addressing this vulnerability. Users should upgrade to ColdFusion 2021 Update 23 or later, ColdFusion 2023 Update 17 or later, or ColdFusion 2025 Update 5 or later. As interim mitigations, administrators should restrict and validate all serialized data inputs, enforce strict access controls for high-privileged accounts, implement network segmentation to limit exposure of the ColdFusion admin interface, and monitor deserialization activity for anomalies. Applying the vendor patch is the recommended and definitive remediation (Adobe Advisory).

The vulnerability was covered as part of Adobe's December 2025 Patch Tuesday release, which addressed multiple products. Sophos noted the December 2025 Patch Tuesday as a significant end-of-year patching event, and CIS issued an advisory on multiple Adobe vulnerabilities allowing arbitrary code execution. Coverage has been largely routine, with no notable researcher commentary or significant social media discussion specific to this CVE (Sophos Blog, CIS Advisory).
