Summary
A local attacker without logging in can run arbitrary code in OriginLab Origin Viewer by getting a user to open a malicious OGWU file, which triggers an out-of-bounds write during parsing. The flaw comes from missing validation of user-supplied data in the file parser.

Read the original description
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.
Who should check
Teams running OriginLab Origin Viewer, including users who open OGWU files from untrusted sources.

What to do
Check whether your setup matches what the bug needs.
Origin Viewer parsing OGWU filesWorkaround: No fix is listed in the facts. Avoid opening OGWU files from untrusted or unknown sources until the vendor publishes a fix.
Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-114562 (OriginLab Origin Viewer OGWU File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability), using the cve.now data below.
Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.
What cve.now has for CVE-2026-114562 (entry last updated 2026-11-12):
Affected:
- OriginLab Origin Viewer: versions 9.9.5
Fixed versions: none listed yet.
Conditions (all must be true for the bug to be hit):
- Origin Viewer parsing OGWU files (source: https://www.zerodayinitiative.com/advisories/ZDI-26-879/)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: local access, no login, a user action.
CISA KEV: CVE-2026-114562 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-114562 only. If you also check another CVE, look up its own KEV status; never assume it from this one.
How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.
Verify against the linked advisories before concluding, and cite the date you read each one:
- https://docs.originlab.com/cve/CVE-2026-114562
- https://www.zerodayinitiative.com/advisories/ZDI-26-879/
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.
Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

Questions about CVE-2026-114562
Is CVE-2026-114562 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
The flaw is an out-of-bounds write in how OriginLab Origin Viewer parses OGWU files. An attacker can use it to run code in the context of the current Origin Viewer process.Source: zerodayinitiative.com
Which versions are affected by CVE-2026-114562?
Origin Viewer: version 9.9.5.Source: cve.now feed data
Am I affected, and how do I check?
The facts list no affected version ranges, only OriginLab Origin Viewer when it parses OGWU files. To check your own setup, look at the installed Origin Viewer version and whether it opens OGWU files, then compare against the vendor's advisory.Source: zerodayinitiative.com
How do I fix CVE-2026-114562?
The facts name no fixed version or vendor patch identifiers, so no upgrade target can be given. Check the vendor's advisory for an update before relying on any particular version.Source: zerodayinitiative.com
What if there's no patch?
No fix is listed in the facts. Avoid opening OGWU files from untrusted or unknown sources until the vendor publishes a fix.Source: zerodayinitiative.com
Why do the sources disagree?
The description says the flaw can be reached remotely, but the CVSS vector records a local attack vector (AV:L). The sources do not reconcile how the file is delivered to the victim.Source: zerodayinitiative.com
