CVE-2025-61800 is an integer overflow or wraparound vulnerability (CWE-190) identified in Adobe Dimension versions 4.1.4 and earlier. This vulnerability arises when the software improperly handles integer values, leading to an overflow condition that can corrupt memory or cause unexpected behavior. Specifically, a crafted malicious file can trigger this overflow, enabling an attacker to execute arbitrary code within the context of the current user. The attack vector requires user interaction, meaning the victim must open a malicious file for exploitation to succeed. The vulnerability does not require prior authentication, increasing its risk profile if users are tricked into opening compromised files. The CVSS v3.1 base score is 7.8, reflecting high severity due to the combination of local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), required user interaction (UI:R), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No patches or exploit code are currently publicly available, but the vulnerability is officially published and reserved by Adobe. This flaw could be leveraged by attackers to gain control over affected systems, potentially leading to data theft, system compromise, or disruption of services.

For European organizations, particularly those in creative, design, and digital media sectors that utilize Adobe Dimension, this vulnerability poses a significant risk. Successful exploitation can lead to arbitrary code execution, allowing attackers to steal sensitive intellectual property, manipulate design assets, or deploy malware within corporate networks. The impact extends to confidentiality breaches, integrity violations of design files, and potential denial of service if systems become unstable or compromised. Since exploitation requires user interaction, phishing or social engineering campaigns could be used to deliver malicious files. The widespread use of Adobe products in Europe, combined with the high severity of this vulnerability, means that organizations could face operational disruptions and reputational damage if targeted. Additionally, compromised endpoints could serve as footholds for broader network intrusions.

Organizations should prioritize patching Adobe Dimension once Adobe releases an official update addressing CVE-2025-61800. Until patches are available, implement strict controls on file sources by restricting the opening of files from untrusted or unknown origins. Employ endpoint protection solutions with advanced behavior-based detection to identify and block suspicious activities related to file parsing and code execution. Conduct user awareness training focused on recognizing phishing attempts and the risks of opening unsolicited files. Implement application whitelisting to limit execution of unauthorized code. Network segmentation can reduce lateral movement if a system is compromised. Regularly back up critical design files and maintain incident response plans tailored to endpoint compromise scenarios. Monitoring for anomalous process behavior related to Adobe Dimension can provide early detection of exploitation attempts.
