{"id":"CVE-2026-114562","kind":"vulnerability","aliases":["CVE-2026-114562"],"related":[],"title":"OriginLab Origin Viewer: crafted OGWU file lets attackers run 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 before the start of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-30736.","summary":"Origin Viewer has an out-of-bounds write (a write before the start of an allocated buffer) when it parses OGWU files. A user who opens a crafted file or visits a malicious page can let an attacker run code as that user.
