{"id":"CVE-2026-85288","published":"2026-09-22T18:17:23.373","lastModified":"2026-09-26T00:16:37.387","description":"Notepad++ is a free and open-source source code editor. Prior to 8.9.8, Notepad++ incompletely enforces shortcuts.xml HMAC validation because WM_MACRODLGRUNMACRO, the Run a Macro Multiple Times entry point, calls macroPlayback() without the validation used by command(). A tampered shortcuts.xml macro that is blocked through the Macro menu or a shortcut key can therefore execute through the multi-run dialog and invoke internal Notepad++ commands, including commands that launch external programs, in the current user context. This issue is fixed in version 8.9.8.","cvssScore":6.7,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-78","CWE-345","CWE-693"],"vendors":[],"products":[],"references":[{"url":"https://github.com/notepad-plus-plus/notepad-plus-plus/commit/4cd74cb9347b9c6caaab17d999e24fc9ed228ff7","tags":[]},{"url":"https://github.com/notepad-plus-plus/notepad-plus-plus/releases/tag/v8.9.8","tags":[]},{"url":"https://github.com/notepad-plus-plus/notepad-plus-plus/security/advisories/GHSA-759j-g8j4-867p","tags":[]},{"url":"https://notepad-plus-plus.org/news/v898-released","tags":[]},{"url":"https://github.com/notepad-plus-plus/notepad-plus-plus/security/advisories/GHSA-759j-g8j4-867p","tags":[]}],"exploitRefs":[{"url":"https://github.com/notepad-plus-plus/notepad-plus-plus/commit/4cd74cb9347b9c6caaab17d999e24fc9ed228ff7","tags":[]},{"url":"https://github.com/notepad-plus-plus/notepad-plus-plus/releases/tag/v8.9.8","tags":[]},{"url":"https://github.com/notepad-plus-plus/notepad-plus-plus/security/advisories/GHSA-759j-g8j4-867p","tags":[]},{"url":"https://github.com/notepad-plus-plus/notepad-plus-plus/security/advisories/GHSA-759j-g8j4-867p","tags":[]}],"hasPoc":true,"ai":null}
