Technical details
The vulnerability is an out-of-bounds write (buffer overflow) in the OPJ file parsing logic caused by insufficient validation of user-supplied data. Attack vector is local with user interaction required—the victim must open a specially crafted OPJ file. An attacker can leverage this to execute arbitrary code in the context of the current user. The vulnerability affects OriginPro versions 2026b SR0 and earlier; a fix is available in version 2026b SR1 and later.
