{"id":"CVE-2026-114567","kind":"vulnerability","aliases":["CVE-2026-114567"],"related":[],"title":"OriginLab Origin Viewer: opening a crafted OGWU file can run attacker code","description":"OriginLab Origin Viewer OGWU File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of OriginLab Origin Viewer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.\n\nThe specific flaw exists within the parsing of OGWU 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-30771.","summary":"Origin Viewer (Windows) writes past the end of an allocated structure when parsing a crafted OGWU file. An attacker who gets a user to open a malicious file (or visit a page that delivers one) can run code as that user.
