CVE-2026-32926 is an out-of-bounds read vulnerability identified in the V-SFT software developed by FUJI ELECTRIC CO., LTD. and Hakko Electronics Co., Ltd. The vulnerability resides in the function VS6ComFile!load_link_inf, which improperly handles input when processing V7 files. Specifically, when a crafted V7 file is opened, the function reads memory outside the intended buffer boundaries, potentially exposing sensitive information from the application's memory space. This can lead to information disclosure, compromising confidentiality, and may also affect integrity and availability due to the nature of the memory corruption. The vulnerability affects all V-SFT versions up to and including 6.2.10.0. Exploitation requires user interaction (opening the malicious file) but does not require prior authentication or elevated privileges, making it accessible to local users or attackers who can trick users into opening the file. The CVSS v3.1 base score is 7.8, reflecting high severity with vector metrics indicating local attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability. No public exploits have been reported yet, but the vulnerability's characteristics suggest it could be leveraged for targeted attacks or espionage, especially in industrial environments where V-SFT is used for automation and control systems.

The primary impact of CVE-2026-32926 is unauthorized disclosure of sensitive information from the affected V-SFT application memory, which could include configuration data, credentials, or operational parameters critical to industrial control systems. This information leakage can facilitate further attacks such as privilege escalation, unauthorized control, or sabotage of industrial processes. The integrity and availability of the system may also be compromised due to memory corruption, potentially causing crashes or erratic behavior in automation workflows. Organizations relying on V-SFT for industrial automation, manufacturing process control, or monitoring are at risk of operational disruption, intellectual property theft, and safety hazards. Given the widespread use of FUJI ELECTRIC and Hakko Electronics products in manufacturing sectors, the threat could have significant economic and safety implications. The requirement for user interaction limits remote exploitation but does not eliminate risk, especially in environments where file sharing or external media use is common. The absence of known exploits currently provides a window for proactive mitigation before active attacks emerge.

1. Immediate upgrade to the latest V-SFT version beyond 6.2.10.0 once patches are released by FUJI ELECTRIC or Hakko Electronics. 2. Until patches are available, implement strict file handling policies to prevent opening untrusted or unsolicited V7 files, including disabling automatic file opening features. 3. Employ application whitelisting and endpoint protection solutions to detect and block attempts to open crafted files. 4. Conduct user awareness training focused on the risks of opening files from unknown or untrusted sources, especially in industrial environments. 5. Isolate V-SFT systems from general-purpose networks to limit exposure to malicious files. 6. Monitor logs and system behavior for anomalies indicative of exploitation attempts or memory corruption. 7. Use network segmentation and access controls to restrict local access to V-SFT systems only to authorized personnel. 8. Coordinate with vendors for timely security advisories and updates. 9. Consider deploying runtime application self-protection (RASP) or memory protection technologies if supported by the environment to mitigate out-of-bounds read risks.
