CVE-2025-47134 is a heap-based buffer overflow vulnerability (CWE-122) identified in Adobe InDesign Desktop versions 19.5.3 and earlier. The flaw arises from improper handling of memory buffers when processing certain crafted input within InDesign files, leading to a buffer overflow on the heap. This memory corruption can be exploited by an attacker to execute arbitrary code in the context of the current user. The attack vector requires user interaction, specifically opening a maliciously crafted InDesign file, which triggers the overflow condition. The vulnerability does not require prior authentication, increasing its risk profile. The CVSS v3.1 base score of 7.8 reflects high impact on confidentiality, integrity, and availability, with low attack complexity but requiring user interaction. Although no public exploits have been reported yet, the vulnerability’s characteristics make it a prime candidate for targeted attacks, especially in creative and publishing environments that rely heavily on Adobe InDesign. The absence of available patches at the time of disclosure increases exposure. The vulnerability’s exploitation could lead to full system compromise under the privileges of the user running InDesign, enabling data theft, malware installation, or lateral movement within networks.

The potential impact of CVE-2025-47134 is significant for organizations worldwide, particularly those in media, publishing, graphic design, and advertising sectors that extensively use Adobe InDesign Desktop. Successful exploitation can lead to arbitrary code execution, allowing attackers to compromise user systems, steal sensitive data, or deploy malware such as ransomware. Since the vulnerability affects the confidentiality, integrity, and availability of systems, it could disrupt business operations and damage organizational reputation. The requirement for user interaction limits mass exploitation but does not eliminate risk, especially in environments where users frequently open files from external or untrusted sources. The lack of authentication requirement means any user with access to the vulnerable software is at risk. Additionally, compromised endpoints could serve as footholds for broader network intrusions. The absence of known exploits currently provides a window for proactive defense, but organizations must act swiftly to prevent future attacks once exploit code becomes available.

1. Monitor Adobe’s official channels closely for patches addressing CVE-2025-47134 and apply updates immediately upon release. 2. Until patches are available, restrict users from opening InDesign files from untrusted or unknown sources, including email attachments and downloads. 3. Implement application whitelisting and sandboxing to limit the execution scope of InDesign and reduce the impact of potential exploitation. 4. Employ endpoint detection and response (EDR) solutions capable of identifying anomalous behaviors associated with heap-based buffer overflow exploitation. 5. Conduct user awareness training emphasizing the risks of opening unsolicited or suspicious files, particularly in creative departments. 6. Use network segmentation to isolate systems running Adobe InDesign from critical infrastructure to limit lateral movement if compromise occurs. 7. Regularly back up critical data and verify backup integrity to enable recovery in case of ransomware or data corruption resulting from exploitation. 8. Review and harden system privileges to minimize the impact of code execution under user context, including avoiding running InDesign with administrative rights.
