# OriginLab Origin Viewer: opening a crafted OGWU file can run attacker code

Link for people: https://infrastack.ai/live/CVE-2026-114567 (this .md is for agents)

Origin Viewer (Windows) writes past the end of an allocated structure when parsing a crafted OGWU file. An attacker who gets a user to open a malicious file (or visit a page that delivers one) can run code as that user. ZDI says OriginLab has issued an update but names no version; no exploitation or public PoC found.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:OriginLab Origin Viewer affected range not listed fixed no fixed version listed
- vendor:Origin Viewer affected unknown (Windows viewer; builds before the fix) fixed no fixed version listed

## How to check

Check the installed Origin Viewer version (Help > About). The latest build in the vendor release notes is 10.4.0.25 (2026-07-30), but those notes do not list this CVE, so confirm the fixed build on https://docs.originlab.com/cve/CVE-2026-114567 (404 when checked 2026-11-12) or with OriginLab. Also check whether users open OPJU/OGWU files from untrusted sources.

## Fix

OriginLab says an update exists (per ZDI-26-884); fixed version not stated in any page read. Install the newest Origin Viewer from OriginLab and confirm against the vendor CVE page.

- 2026-11-12T03:52:03+00:00 analyst https://www.zerodayinitiative.com/advisories/ZDI-26-884/ — ZDI-26-884 (rgod, CVSS 7.8, reported 2026-06-02, published 2026-11-06) confirms OGWU out-of-bounds write; says OriginLab issued an update but gives no version. Vendor page docs.originlab.com/cve/CVE-2026-114567 returned 404/empty; release notes list 10.4.0.25 (7/30/2026) fixing other CVEs but not this one. Fixed version unknown. Nothing verified (no vendor primary text).

## From the sources

OriginLab Origin Viewer OGWU File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of OriginLab Origin Viewer. 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 OGWU 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-30771.
