{"id":"CVE-2026-77605","published":"2026-09-22T18:17:19.393","lastModified":"2026-09-28T18:17:25.143","description":"Notepad++ is a free and open-source source code editor. Prior to 8.9.8, the Folder as Workspace Run by system action in Notepad++ can resolve a different sibling file than the file selected by the user. When an attacker places a command script whose name is the selected text-file path with .cmd appended, and the user invokes Run by system on the text file on Windows 10 or Windows 11, Notepad++ can execute the sibling script as the current user instead of opening the selected file. This issue is fixed in version 8.9.8.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-20","CWE-706"],"vendors":[],"products":[],"references":[{"url":"https://github.com/notepad-plus-plus/notepad-plus-plus/commit/00fa5df0da1d4f6b334317aa979db13ac77ee24d","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-w5xq-frjg-w4cw","tags":[]},{"url":"https://notepad-plus-plus.org/news/v898-released","tags":[]},{"url":"https://github.com/notepad-plus-plus/notepad-plus-plus/security/advisories/GHSA-w5xq-frjg-w4cw","tags":[]}],"exploitRefs":[{"url":"https://github.com/notepad-plus-plus/notepad-plus-plus/commit/00fa5df0da1d4f6b334317aa979db13ac77ee24d","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-w5xq-frjg-w4cw","tags":[]},{"url":"https://github.com/notepad-plus-plus/notepad-plus-plus/security/advisories/GHSA-w5xq-frjg-w4cw","tags":[]}],"hasPoc":true,"ai":null}
