Prior to 8.9.6.1, the <GUIConfig name=\"commandLineInterpreter\"> tag in config.xml is read by NppXml::value() (Parameters.cpp:6430) and stored in _nppGUI._commandLineInterpreter without any validation, whitelist, or digital signature check. When the user triggers IDM_FILE_OPEN_CMD (File → Open Containing Folder → cmd), NppCommands.cpp:228 creates a Command object with this value and calls run(), which invokes ShellExecute (RunDlg.cpp:221) with the attacker-controlled string as the executable path. This vulnerability is fixed in 8.9.6.1.","published":"2026-06-26T21:16:34.000Z","lastModified":"2026-06-29T21:22:02.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-78"],"affected":["notepad-plus-plus/notepad\\+\\+"],"epss":{"score":0.0062,"percentile":0.49505,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2026-05-30","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":52606,"kind":"exploit","title":"Notepad++ 8.9.6 - Arbitrary Code Execution","url":"https://www.exploit-db.com/exploits/52606","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/windows/remote/52606.py","file":"exploits/windows/remote/52606.py","published":"2026-05-30","added":"2026-05-30","updated":"2026-05-30","author":"Kavin Jindal","type":"remote","platform":"windows","port":null,"verified":false,"codes":["CVE-2026-48778"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"A public exploit is published in Exploit-DB and the impact is high, while EPSS rates exploitation at 0.6%.
