OriginLab OriginPro OPJU 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 OPJU 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-29331.
AnalysisAI
Remote code execution is achievable in OriginLab OriginPro through a maliciously crafted OPJU project file, exploiting an out-of-bounds write (CWE-787) in the application's file parser. OriginPro 2026 SR1 is confirmed affected per EUVD-2026-63436, with the CPE string suggesting broader version coverage may apply. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively open a maliciously crafted OPJU file using OriginLab OriginPro (OriginPro 2026 SR1 confirmed affected). … 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) accurately captures the threat model: exploitation is constrained to a local file-open event requiring active user interaction, but once the file is opened, attack complexity is low and impact is full across confidentiality, integrity, and availability. … 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 | Users should consult the vendor advisory at https://docs.originlab.com/cve/CVE-2026-18288 immediately to obtain the patched release, as the exact fixed version number is not independently confirmed from the available intelligence data - the advisory should specify the corrected build. … Detailed patch versions, workarounds, and compensating controls in full report. |
