# OriginLab Origin Viewer: crafted OGWU file lets attackers run code

Link for people: https://infrastack.ai/live/CVE-2026-114562 (this .md is for agents)

Origin Viewer has an out-of-bounds write (a write before the start of an allocated buffer) when it parses OGWU files. A user who opens a crafted file or visits a malicious page can let an attacker run code as that user. ZDI says OriginLab has issued an update, but the fixed version is not published in pages I could read.

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

## Affected

- vendor:Origin Viewer affected range not listed fixed no fixed version listed

## How to check

In Origin Viewer (Windows) open Help > About and note the version. The affected range for this CVE is not published in the pages I could read. Release notes list 10.4.0.25 (2026-07-30) as latest, but they do not name this CVE. Read the vendor page https://docs.originlab.com/cve/CVE-2026-114562 for the fixed build. Treat .ogwu files from untrusted sources as unsafe until updated.

## Fix

OriginLab says it has issued an update (per ZDI-26-879); the fixed version is unknown. See https://docs.originlab.com/cve/CVE-2026-114562. Install the latest Origin Viewer from OriginLab meanwhile.

ZDI says OriginLab issued an update, linking docs.originlab.com/cve/CVE-2026-114562, which I could not retrieve. Release notes for 10.4.0.25 list only four other CVEs, not this one. Affected range and fixed version unconfirmed; nothing verified. No exploitation or PoC seen.

## 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 before the start of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-30736.
