CVE-2025-54225 is a Use After Free (CWE-416) vulnerability affecting Adobe InDesign Desktop versions 20.4, 19.5.4, and earlier. The vulnerability arises when the application improperly manages memory, leading to a scenario where freed memory is accessed, potentially allowing an attacker to execute arbitrary code. This occurs in the context of the current user, meaning the attacker gains the same privileges as the user running InDesign. Exploitation requires user interaction, specifically opening a maliciously crafted InDesign file, which triggers the memory corruption. The vulnerability does not require prior authentication, increasing its risk profile. The CVSS v3.1 base score is 7.8, with vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating local attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability. No patches or exploit code are currently publicly available, but the vulnerability is published and recognized by Adobe and the CVE database. This vulnerability poses a significant risk to users of affected InDesign versions, especially in environments where malicious files could be introduced via email, file sharing, or compromised websites.

The impact of CVE-2025-54225 is substantial for organizations using Adobe InDesign Desktop, particularly in creative industries such as publishing, advertising, and media production. Successful exploitation allows attackers to execute arbitrary code, potentially leading to data theft, system compromise, or disruption of services. Since the code runs with the current user's privileges, the attacker could access sensitive documents, install malware, or move laterally within a network if the user has elevated rights. The requirement for user interaction limits remote exploitation but does not eliminate risk, as social engineering or phishing campaigns could deliver malicious files. The vulnerability affects confidentiality by exposing sensitive content, integrity by allowing unauthorized code execution, and availability by potentially crashing or disabling the application or system. Organizations with high reliance on InDesign for critical workflows may face operational disruptions and reputational damage if exploited.

To mitigate CVE-2025-54225, organizations should implement the following specific measures: 1) Monitor Adobe’s official channels for patches and apply updates immediately upon release to remediate the vulnerability. 2) Restrict the opening of InDesign files from untrusted or unknown sources, including email attachments and downloads, through user training and technical controls. 3) Employ application whitelisting and sandboxing to limit the ability of malicious code to execute or affect other system components. 4) Use endpoint detection and response (EDR) solutions to identify suspicious behaviors related to InDesign processes. 5) Enforce the principle of least privilege for users running InDesign to minimize the impact of potential exploitation. 6) Implement network segmentation to contain any compromise resulting from exploitation. 7) Educate users on recognizing phishing and social engineering attempts that could deliver malicious files. These targeted actions go beyond generic advice and address the specific attack vector and impact of this vulnerability.
