Description
OriginLab OriginPro OPJ File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of OriginLab OriginPro. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of OPJ files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29332.

Executive Summary

CVE-2026-18289 is an out-of-bounds write vulnerability in OriginLab OriginPro that allows remote code execution. It occurs when parsing specially crafted OPJ project files due to improper validation of user-supplied data. This flaw can lead to a write past the end of an allocated data structure, enabling attackers to execute arbitrary code in the context of the current process.

Detection Guidance

Detecting this vulnerability requires checking the installed version of OriginLab OriginPro. Compare your version against Origin 2026b SR1 or later. If you are running an earlier version, the system is likely vulnerable. No specific commands are provided in the resources to detect exploitation attempts.

Impact Analysis

This vulnerability allows attackers to execute arbitrary code on your system if you open a malicious OPJ file or visit a malicious page. It can compromise your data, install malware, or give attackers control over your system. The impact depends on your system's privileges and the actions taken by the attacker.

Compliance Impact

This vulnerability could lead to unauthorized code execution, potentially allowing attackers to access, modify, or exfiltrate sensitive data. This may violate compliance requirements under GDPR (data protection) and HIPAA (health information privacy) by enabling data breaches or unauthorized data processing.

Mitigation Strategies

Update OriginLab OriginPro to version 2026b SR1 or later immediately. Avoid opening OPJ project files from untrusted sources. Ensure users are aware of the risk of malicious files and exercise caution when handling them.
