CVE-2025-61812: 
Adobe ColdFusion vulnerability analysis and mitigation

CVE-2025-61812 is an Improper Input Validation vulnerability (CWE-20) in Adobe ColdFusion that allows a high-privileged attacker to achieve arbitrary code execution without user interaction. It affects ColdFusion versions 2025.4, 2023.16, 2021.22 and all earlier releases across the 2021, 2023, and 2025 product lines. The vulnerability was disclosed on December 9, 2025, with NVD publication on December 10, 2025. It carries a CVSS v3.1 base score of 8.4 (High), assigned by Adobe Systems Incorporated (Adobe Advisory, NVD).

The vulnerability is classified as CWE-20 (Improper Input Validation), meaning the application fails to adequately validate attacker-supplied input before processing it in a security-sensitive context. The attack vector is Adjacent Network (AV:A), requiring the attacker to be on the same network segment or logical network as the target ColdFusion server, and high privileges (PR:H) are required to initiate exploitation. The scope is changed (S:C), indicating that successful exploitation can impact resources beyond the vulnerable component itself. No public proof-of-concept or detailed technical write-up has been published as of the disclosure date (Adobe Advisory, NVD).

Successful exploitation allows a high-privileged attacker to execute arbitrary code on the affected ColdFusion server, resulting in full compromise of confidentiality, integrity, and availability (all rated High). Because the scope is changed, the impact can extend beyond the ColdFusion instance itself to other systems accessible from the compromised server, enabling potential lateral movement within the network. Sensitive data hosted or accessible by the ColdFusion application — including application credentials, database contents, and configuration files — may be exposed or manipulated (Adobe Advisory, NVD).

Adobe has released patched versions addressing this vulnerability: ColdFusion 2025 Update 5, ColdFusion 2023 Update 17, and ColdFusion 2021 Update 23 (or later). Organizations should apply the relevant update immediately per Adobe Security Bulletin APSB25-105. As interim mitigations, administrators should restrict high-privilege account access, implement network segmentation to limit adjacent network exposure to ColdFusion servers, and monitor privileged account activity for anomalies (Adobe Advisory).

The vulnerability was noted in Sophos's December 2025 Patch Tuesday roundup as part of Adobe's broader December security release (Sophos Blog). The Center for Internet Security (CIS) issued an advisory flagging multiple Adobe vulnerabilities in the same release cycle as potentially allowing arbitrary code execution (CIS Advisory). No significant independent researcher commentary or social media discussion specific to CVE-2025-61812 has been identified beyond standard vulnerability tracking and aggregation activity.
