CVE-2025-47106 is a Use After Free (CWE-416) vulnerability affecting Adobe InDesign Desktop versions ID20.2, ID19.5.3, and earlier. This vulnerability arises when the application improperly manages memory, specifically by accessing memory after it has been freed. Such a flaw can lead to disclosure of sensitive memory contents. In this case, an attacker could exploit the vulnerability to bypass security mitigations like Address Space Layout Randomization (ASLR), which is designed to prevent predictable memory address exploitation. The exploitation requires user interaction, specifically that the victim opens a crafted malicious InDesign file. The vulnerability does not directly allow code execution or denial of service but can leak sensitive memory data, potentially aiding further attacks. The CVSS v3.1 base score is 5.5 (medium severity), reflecting that the attack vector is local (requires user interaction and local access), with low attack complexity, no privileges required, and no impact on integrity or availability, but high impact on confidentiality. No known exploits are currently reported in the wild, and no patches have been linked yet. This vulnerability is significant because Adobe InDesign is widely used in creative industries for desktop publishing, and leaking sensitive memory could expose confidential project data or user information.

For European organizations, especially those in media, publishing, advertising, and design sectors that rely heavily on Adobe InDesign Desktop, this vulnerability poses a risk of sensitive data leakage. Confidential client information, intellectual property, or internal project details could be exposed if a malicious file is opened. While the vulnerability does not allow direct code execution, the ability to bypass ASLR could facilitate more advanced exploitation chains if combined with other vulnerabilities. This could increase the risk of targeted attacks against creative agencies, marketing firms, and publishing houses in Europe. Additionally, organizations handling sensitive or regulated data (e.g., GDPR-protected personal data) could face compliance and reputational risks if such data is leaked. The requirement for user interaction means phishing or social engineering campaigns could be used to deliver malicious files, increasing the attack surface. The medium severity score suggests a moderate risk, but the potential for escalation in multi-stage attacks should not be underestimated.

European organizations should implement the following specific mitigations: 1) Educate users in creative and publishing departments about the risks of opening unsolicited or unexpected InDesign files, emphasizing cautious handling of email attachments and downloads. 2) Employ strict email filtering and sandboxing solutions to detect and block malicious InDesign files before reaching end users. 3) Monitor and restrict the use of older InDesign Desktop versions (ID20.2, ID19.5.3, and earlier) and plan for rapid deployment of patches once Adobe releases them. 4) Use endpoint detection and response (EDR) tools to identify suspicious behaviors related to memory access or exploitation attempts. 5) Implement application whitelisting and restrict execution privileges to limit the impact of potential exploitation. 6) Maintain regular backups of critical design projects to mitigate data loss risks. 7) Coordinate with Adobe support channels to receive timely updates and patches. Since no patch is currently linked, organizations should prioritize risk assessment and user training until a fix is available.
