CVE-2025-7988 is a high-severity vulnerability classified under CWE-787 (Out-of-bounds Write) affecting Ashlar-Vellum Graphite version 13.0. The flaw arises from improper validation of user-supplied data during the parsing of VC6 files, leading to a write operation beyond the allocated buffer boundaries. This memory corruption can be exploited by remote attackers to execute arbitrary code within the context of the current process. Exploitation requires user interaction, specifically the victim opening a maliciously crafted VC6 file or visiting a malicious webpage that triggers the vulnerable parser. The vulnerability does not require prior authentication but does require low attack complexity and user interaction. The CVSS 3.0 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability. Although no public exploits are currently known in the wild, the nature of the vulnerability—remote code execution via file parsing—makes it a significant risk, especially in environments where Graphite is used to handle VC6 files. The lack of a patch link suggests that a fix may not yet be publicly available or is pending release. Organizations using Ashlar-Vellum Graphite 13.0 should consider this vulnerability critical to address promptly to prevent potential compromise.

For European organizations, this vulnerability poses a substantial risk, particularly for industries relying on Ashlar-Vellum Graphite for CAD or design workflows involving VC6 files. Successful exploitation could lead to full system compromise, data theft, or disruption of critical design operations. Confidentiality is at risk as attackers could access sensitive design data; integrity is compromised through arbitrary code execution allowing modification or destruction of files; availability could be impacted if attackers deploy ransomware or cause system crashes. Given the requirement for user interaction, phishing or social engineering campaigns could be leveraged to deliver malicious files or links. The impact is amplified in sectors such as manufacturing, engineering, and architecture, where design data is both sensitive and critical to business operations. Additionally, the potential for lateral movement within networks after initial compromise could threaten broader organizational infrastructure.

Beyond standard patching once available, European organizations should implement strict file handling policies, including disabling automatic opening or previewing of VC6 files in email clients and browsers. Employ advanced endpoint protection capable of detecting anomalous behavior related to memory corruption exploits. Network segmentation should isolate systems running Ashlar-Vellum Graphite to limit lateral movement. User awareness training should emphasize the risks of opening unsolicited files or links, particularly those related to VC6 files. Employ application whitelisting to restrict execution of unauthorized code. Monitoring and logging of file access and process behavior on systems running Graphite can provide early detection of exploitation attempts. If patching is delayed, consider using sandboxing or virtualized environments for handling untrusted VC6 files to contain potential exploitation.
