Summary
OriginLab Origin Viewer has a stack-based buffer overflow when parsing OGWU files, caused by copying user-supplied data without checking its length. An attacker who gets a user to open a malicious file or visit a malicious page locally, without logging in, could run arbitrary code in the context of the current process.

Read the original description
OriginLab Origin Viewer OGWU File Parsing Stack-based Buffer Overflow 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 the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-30737.
Who should check
Teams running OriginLab Origin Viewer and anyone opening OGWU files from untrusted sources

What to do
Check whether your setup matches what the bug needs.
Affected product is OriginLab Origin Viewer, processing OGWU files.Workaround: The checked facts record no fix and no workaround. Until a fix or workaround is published, the checked facts give no mitigation to follow.
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-2026-114563 (OriginLab Origin Viewer OGWU File Parsing Stack-based Buffer Overflow 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-2026-114563 (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):
- Affected product is OriginLab Origin Viewer, processing OGWU files. (source: https://www.zerodayinitiative.com/advisories/ZDI-26-880/)
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-2026-114563 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-114563 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-2026-114563
- https://www.zerodayinitiative.com/advisories/ZDI-26-880/
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-2026-114563
Is CVE-2026-114563 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 a stack-based buffer overflow in how Origin Viewer parses OGWU files. The source says it can let an attacker execute code in the context of the current process.Source: zerodayinitiative.com
Which versions are affected by CVE-2026-114563?
Origin Viewer: version 9.9.5.Source: cve.now feed data
Am I affected, and how do I check?
The affected product is OriginLab Origin Viewer when it processes OGWU files. The checked facts list no affected version ranges, so the version to check against the vendor's advisory cannot be confirmed here.Source: zerodayinitiative.com
How do I fix CVE-2026-114563?
The checked facts name no fixed version and no vendor patch identifiers, so no upgrade target can be given. The vendor's advisory should be checked for a fix.Source: zerodayinitiative.com
What if there's no patch?
The checked facts record no fix and no workaround. Until a fix or workaround is published, the checked facts give no mitigation to follow.Source: zerodayinitiative.com
Why do the sources disagree?
The description says the vulnerability can be triggered remotely, while the CVSS vector lists the attack vector as local (AV:L). The checked facts do not resolve which of these is correct.Source: zerodayinitiative.com
