OriginLab OriginPro OPJ 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 OPJ 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-29332.
AnalysisAI
Out-of-bounds write in OriginPro's OPJ project file parser enables remote attackers to execute arbitrary code when a user opens a specially crafted OPJ file. The flaw, disclosed by Zero Day Initiative as ZDI-CAN-29332, results from insufficient validation of user-supplied data during file parsing - allowing a write past the end of an allocated data structure and full compromise of the target process. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target system is running OriginLab OriginPro 2026 SR1 (the version confirmed by EUVD-2026-63437) and that the victim actively opens a specially crafted OPJ project file. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.8 score reflects a local-vector attack (AV:L) with no attacker privileges required (PR:N), low complexity (AC:L), mandatory user interaction (UI:R), and full C/I/A impact. … 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-2026-18289 for the official patch and exact fixed version number - no specific patched release was included in the available intelligence and inventing a version number would be inappropriate. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Issue security advisory to all OriginPro users instructing them to avoid opening OPJ files from untrusted sources and external communication channels; restrict file downloads to approved internal sources only. …
