CVE-2026-18294

Arbitrary code execution via malformed OGW parsing

Published Aug 20, 2026 · Updated Aug 20, 2026

Memory corruption in OriginLab Origin Viewer 9.9.5 and earlier allows remote attackers to execute code via a crafted OGW project file. The OGW file parser fails to validate attacker-controlled data before using it during parsing, causing memory corruption in the current process. Exploitation requires the logged-in user to visit malicious content or open the file, after which code runs with that user's privileges.
