CVE-2025-61814 is a Use After Free (CWE-416) vulnerability affecting 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 arbitrary code execution. An attacker can exploit this flaw by crafting a malicious InDesign file that, when opened by a user, triggers the use-after-free condition. This allows the attacker to execute code within the context of the current user, potentially leading to full compromise of the user's environment depending on their privileges. The vulnerability requires user interaction, specifically opening the malicious file, and does not require prior authentication or elevated privileges. The CVSS 3.1 base score is 7.8, reflecting high severity due to the potential for complete compromise of confidentiality, integrity, and availability. No patches or updates have been released at the time of publication, and there are no known exploits in the wild, indicating that the threat is currently theoretical but could become active once weaponized. Adobe InDesign is widely used in creative and publishing industries, making this vulnerability particularly relevant to organizations handling graphic design, publishing, and media production workflows.

For European organizations, the impact of CVE-2025-61814 could be significant, especially for those in sectors relying heavily on Adobe InDesign, such as media, publishing, advertising, and creative agencies. Successful exploitation could lead to unauthorized code execution, allowing attackers to steal sensitive intellectual property, manipulate or destroy design files, or use compromised systems as footholds for further network intrusion. The vulnerability affects confidentiality (exposure of sensitive design data), integrity (tampering with documents), and availability (potential system crashes or denial of service). Since exploitation requires user interaction, phishing or social engineering campaigns could be used to deliver malicious files. The lack of a patch increases risk exposure, and organizations may face operational disruption and reputational damage if exploited. Additionally, attackers could leverage compromised machines to pivot within networks, threatening broader organizational security.

Until Adobe releases an official patch, European organizations should implement several targeted mitigations: 1) Enforce strict email and file attachment filtering to block or quarantine suspicious InDesign files, especially from untrusted sources. 2) Educate users about the risks of opening unsolicited or unexpected InDesign files and encourage verification of file origins. 3) Apply application whitelisting and restrict execution privileges to limit the impact of potential code execution. 4) Use endpoint detection and response (EDR) solutions to monitor for unusual behaviors indicative of exploitation attempts. 5) Isolate systems used for handling InDesign files from critical network segments to reduce lateral movement risk. 6) Maintain up-to-date backups of design files to enable recovery in case of compromise. 7) Monitor Adobe’s security advisories closely and prepare for rapid deployment of patches once available. 8) Consider disabling or restricting InDesign usage on systems where it is not essential.
