CVE-2026-19885 · Severity: high · CVSS 7.8 · Published 2026-09-15

OriginLab Origin Viewer is a data visualization and analysis tool used to open and display scientific data files. This vulnerability allows attackers to execute arbitrary code on a user's computer by crafting a malicious OGWU data file. If a user opens the malicious file, the attacker gains full control over the affected system, potentially enabling data theft, malware installation, or further network compromise.

## Technical details

The vulnerability is an out-of-bounds write flaw in the OGWU file parser of OriginLab Origin Viewer. The parser fails to properly validate user-supplied data when processing OGWU files, leading to a write past the end of an allocated buffer. An attacker can exploit this by crafting a malicious OGWU file that, when opened by a victim, triggers the buffer overflow and allows execution of arbitrary code in the context of the viewer process. The attack requires user interaction (opening a malicious file), and affects Origin Viewer versions prior to 10.4.0.25, which contains the fix.
