OriginLab OriginPro OGW File Parsing Memory Corruption 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 OGW files. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29334.
AnalysisAI
Remote code execution in OriginLab OriginPro 2026 SR1 is triggered when a victim opens a specially crafted OGW workspace file, exploiting a memory corruption flaw in the file parser. The vulnerability, reported by Zero Day Initiative (ZDI-26-550/ZDI-CAN-29334), allows an attacker to execute arbitrary code in the context of the current user process without requiring any privileges on the target system. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target user to actively open a malicious OGW file using OriginLab OriginPro 2026 SR1 (CVSS UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.0 base score of 7.8 with vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H is internally consistent with the description: local file-open delivery, no attacker privileges, single user interaction, and full C/I/A impact if successful. … 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 | The primary remediation is to apply the vendor-issued patch referenced in the OriginLab CVE advisory at https://docs.originlab.com/cve/CVE-2026-18291. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: notify all OriginPro 2026 SR1 users to cease opening workspace files (.OGW) from untrusted or unexpected sources; implement file-based restrictions blocking .OGW file execution through email gateways and endpoint controls. …
