CVE-2025-47099 is a heap-based buffer overflow vulnerability (CWE-122) identified in Adobe InCopy, specifically affecting versions 20.3, 19.5.3, and earlier. The vulnerability arises from improper handling of memory buffers when processing certain file inputs, leading to the possibility of overwriting heap memory. This memory corruption can be exploited by an attacker to execute arbitrary code within the context of the current user. The attack vector requires the victim to open a maliciously crafted InCopy file, making user interaction mandatory for exploitation. The vulnerability does not require prior authentication, increasing its risk profile. The CVSS v3.1 base score of 7.8 reflects high severity, with metrics indicating 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). Although no public exploits have been reported yet, the nature of the vulnerability suggests that once weaponized, it could lead to full compromise of affected systems under the current user context. This vulnerability is particularly critical for organizations relying on Adobe InCopy for content creation and publishing workflows, as it could be leveraged to deploy malware, steal sensitive data, or disrupt operations.

The exploitation of CVE-2025-47099 can have significant impacts on organizations worldwide. Successful attacks could lead to arbitrary code execution, allowing attackers to install malware, steal intellectual property, or manipulate content within publishing environments. Since the vulnerability affects confidentiality, integrity, and availability, it could result in data breaches, unauthorized modifications, and service disruptions. The requirement for user interaction limits mass exploitation but targeted spear-phishing or social engineering campaigns could be effective. Organizations in media, publishing, advertising, and any sector utilizing Adobe InCopy are at heightened risk. Additionally, compromised systems could serve as footholds for lateral movement within corporate networks, amplifying the threat. The absence of known exploits currently provides a window for proactive mitigation, but the high CVSS score underscores the urgency for remediation.

To mitigate CVE-2025-47099, organizations should implement the following specific measures: 1) Monitor Adobe’s official channels for patches and apply updates promptly once released, as no patches are currently available. 2) Enforce strict file handling policies, including disabling automatic opening of InCopy files from untrusted sources and educating users about the risks of opening unsolicited or suspicious files. 3) Utilize application whitelisting and sandboxing techniques to limit the execution environment of Adobe InCopy, reducing the impact of potential exploitation. 4) Deploy endpoint detection and response (EDR) solutions capable of identifying anomalous behavior consistent with exploitation attempts. 5) Conduct regular user awareness training focused on recognizing phishing and social engineering tactics that could deliver malicious InCopy files. 6) Implement network segmentation to isolate systems running Adobe InCopy from critical infrastructure to contain potential breaches. 7) Review and harden user privileges to minimize the impact of code execution under the current user context. These targeted steps go beyond generic advice by focusing on the specific attack vector and operational context of this vulnerability.
