CVE-2025-27196 is a heap-based buffer overflow vulnerability (CWE-122) identified in Adobe Premiere Pro versions 25.1, 24.6.4, and earlier. The vulnerability arises from improper handling of memory buffers when processing certain file inputs, leading to a condition where an attacker can overflow a heap buffer. This overflow can corrupt memory and enable arbitrary code execution within the context of the current user. Exploitation requires the victim to open a maliciously crafted file, which triggers the overflow during file parsing or processing. The vulnerability does not require elevated privileges or authentication, but does require user interaction (opening the file). The CVSS v3.1 base score is 7.8, reflecting high severity with metrics: Attack Vector: Local (user must open file), Attack Complexity: Low, Privileges Required: None, User Interaction: Required, Scope: Unchanged, and high impact on confidentiality, integrity, and availability. No patches or fixes have been publicly linked yet, and no known exploits have been observed in the wild. This vulnerability poses a significant risk to users of Adobe Premiere Pro, particularly those who handle untrusted or external media files. Attackers could leverage this flaw to execute arbitrary code, potentially leading to system compromise, data theft, or disruption of services.

The impact of CVE-2025-27196 is substantial for organizations relying on Adobe Premiere Pro for media editing and production. Successful exploitation can lead to arbitrary code execution with the privileges of the current user, potentially allowing attackers to install malware, steal sensitive data, or disrupt workflows. Since the vulnerability affects confidentiality, integrity, and availability, it could result in unauthorized access to proprietary media content, alteration or deletion of project files, and denial of service conditions. The requirement for user interaction (opening a malicious file) limits remote exploitation but does not eliminate risk, especially in environments where files are shared frequently or received from untrusted sources. Media companies, creative agencies, and enterprises with distributed teams exchanging project files are particularly vulnerable. The absence of known exploits currently provides a window for proactive mitigation, but the high CVSS score indicates that once exploited, the consequences could be severe.

1. Monitor Adobe’s official channels closely for security updates and apply patches immediately once available to remediate the vulnerability. 2. Implement strict file handling policies: restrict opening files from untrusted or unknown sources, and verify file integrity before use. 3. Employ endpoint protection solutions with advanced behavior-based detection to identify and block suspicious activities related to file parsing and memory corruption. 4. Educate users about the risks of opening unsolicited or unexpected media files, emphasizing caution with files received via email or external drives. 5. Use application whitelisting and sandboxing where feasible to limit the impact of potential code execution. 6. Regularly back up critical project files and maintain version control to recover quickly from potential compromise or data loss. 7. Consider network segmentation to isolate systems running Adobe Premiere Pro from sensitive or critical infrastructure to reduce lateral movement risk.
