CVE-2025-61832 is a heap-based buffer overflow vulnerability classified under CWE-122 affecting Adobe InDesign Desktop versions 20.5, 19.5.5, and earlier. The vulnerability arises from improper handling of heap memory when processing certain file inputs, allowing an attacker to overwrite memory buffers. This can lead to arbitrary code execution within the context of the current user, potentially compromising confidentiality, integrity, and availability of the system. Exploitation requires the victim to open a maliciously crafted InDesign file, making user interaction necessary but no authentication is required. The vulnerability has been assigned a CVSS v3.1 base score of 7.8, reflecting high severity due to its impact on all three security properties and relatively low attack complexity. Although no public exploits have been reported yet, the nature of the vulnerability and the widespread use of Adobe InDesign in creative and publishing industries make it a critical concern. Adobe has not yet released patches, so users must rely on interim mitigations. The vulnerability was publicly disclosed on November 11, 2025, with the reservation date on October 1, 2025. Given the software’s role in handling complex document layouts and graphics, exploitation could lead to significant disruption and data compromise in affected environments.

For European organizations, the impact of CVE-2025-61832 is considerable, especially for those in media, publishing, advertising, and design sectors where Adobe InDesign is widely used. Successful exploitation could allow attackers to execute arbitrary code, potentially leading to data theft, unauthorized system control, or disruption of business operations. Since the vulnerability affects the confidentiality, integrity, and availability of systems, it could result in intellectual property loss, reputational damage, and operational downtime. The requirement for user interaction means phishing or social engineering campaigns could be used to deliver malicious files. Organizations with less mature security awareness or lacking robust endpoint protections are at higher risk. Additionally, the lack of available patches at the time of disclosure increases exposure. The threat is amplified in environments where users have elevated privileges or where InDesign is integrated into critical workflows. European regulatory frameworks such as GDPR may impose additional compliance risks if data breaches occur due to exploitation.

1. Immediately implement strict controls on file sources, ensuring that InDesign files are only opened from trusted and verified origins. 2. Educate users about the risks of opening unsolicited or suspicious InDesign files, emphasizing the need for caution with email attachments and downloads. 3. Deploy advanced endpoint detection and response (EDR) solutions capable of identifying anomalous behavior indicative of heap overflow exploitation. 4. Use application whitelisting and sandboxing techniques to limit the execution scope of InDesign and isolate it from sensitive system components. 5. Monitor network traffic for unusual activity that may indicate exploitation attempts or command and control communications. 6. Prepare for rapid deployment of official Adobe patches once released, including testing in staging environments to ensure compatibility. 7. Consider disabling or restricting InDesign usage on systems where it is not essential, reducing the attack surface. 8. Maintain up-to-date backups of critical data to enable recovery in case of compromise. 9. Collaborate with cybersecurity teams to conduct threat hunting focused on this vulnerability and related indicators of compromise. 10. Engage with Adobe support channels for updates and advisories regarding patch availability and mitigation guidance.
