Severity by source
AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
File-parsing flaw requires local user to open a crafted OGG file (AV:L/UI:R); attacker needs no system privileges (PR:N); full process compromise yields high C/I/A with no scope change.

OriginLab OriginPro OGG File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of OriginLab OriginPro. 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 OGG 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-29333.
AnalysisAI
Out-of-bounds write in OriginPro's OGG file parsing component enables arbitrary code execution in the context of the current user's process when a crafted OGG file is opened. Affected installations include OriginPro 2026 SR1, as confirmed by ZDI (ZDI-CAN-29333 / ZDI-26-549) and EUVD-2026-63438. …

Vulnerability AssessmentAI
| Exploitation | The victim must actively open a malicious OGG file in OriginLab OriginPro - user interaction is explicitly required (UI:R per CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.0 score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) reflects high impact to confidentiality, integrity, and availability but is constrained by the local attack vector and required user interaction, meaning automated or wormable exploitation is not viable. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Consult the OriginLab vendor advisory at https://docs.originlab.com/cve/CVE-2026-18290 for the official patched release version; a specific fix version was not independently confirmed in the available intelligence at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all OriginPro 2026 SR1 deployments, implement blocking of OGG file attachments at email gateways, and send security notification to all users advising against opening OGG files from external sources. …
