CVE-2025-61815 is a Use After Free (CWE-416) vulnerability identified in Adobe InDesign Desktop versions 20.5, 19.5.5, and earlier. This vulnerability arises when the software improperly manages memory, freeing an object while it is still in use, which can lead to the execution of arbitrary code. An attacker can exploit this flaw by crafting a malicious InDesign file that, when opened by a user, triggers the use-after-free condition. The vulnerability allows code execution in the context of the current user, potentially compromising confidentiality, integrity, and availability of the affected system. The CVSS v3.1 score is 7.8, indicating high severity, with attack vector local (requiring user interaction), low attack complexity, no privileges required, and user interaction necessary. The scope remains unchanged, meaning the impact is limited to the vulnerable component. Although no public exploits are known at this time, the vulnerability poses a significant risk due to the common use of Adobe InDesign in creative workflows and the ease of delivering malicious files via email or file sharing. The absence of patches at the time of disclosure necessitates immediate attention to mitigation strategies to reduce exposure.

For European organizations, this vulnerability could lead to unauthorized code execution within user contexts, potentially enabling attackers to steal sensitive data, manipulate documents, or disrupt operations. Industries heavily reliant on Adobe InDesign, such as media, publishing, advertising, and graphic design, face elevated risks. The compromise of design files or intellectual property could have reputational and financial consequences. Additionally, attackers might leverage this vulnerability as an initial foothold for lateral movement within corporate networks. Given the requirement for user interaction, phishing or social engineering campaigns could be effective attack vectors. The impact extends to confidentiality breaches, data integrity violations, and possible denial of service if the application crashes. Organizations with remote or hybrid workforces may face increased exposure due to file sharing outside secure environments.

1. Monitor Adobe’s official channels for patches and apply updates immediately upon release. 2. Until patches are available, restrict the opening of InDesign files from untrusted or unknown sources. 3. Implement robust email filtering and phishing awareness training to reduce the risk of malicious file delivery. 4. Employ endpoint detection and response (EDR) solutions with behavior-based detection to identify suspicious activity related to InDesign processes. 5. Use application whitelisting to limit execution of unauthorized code. 6. Enforce the principle of least privilege to minimize the impact of code execution under user accounts. 7. Consider sandboxing or isolating InDesign usage environments to contain potential exploitation. 8. Regularly back up critical design files and maintain version control to recover from potential data corruption or loss.
