{"id":"CVE-2026-48778","summary":"Notepad++: Arbitrary Code Execution via config.xml commandLineInterpreter","details":"Notepad++ is a free and open-source source code editor. Prior to 8.9.6.1, the \u003cGUIConfig name=\"commandLineInterpreter\"\u003e 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.","aliases":["GHSA-7hm3-wp5q-ccv9"],"modified":"2026-07-15T01:49:12.527857178Z","published":"2026-06-26T20:21:17.254Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48778.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-78"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48778.json"},{"type":"ADVISORY","url":"https://github.com/notepad-plus-plus/notepad-plus-plus/security/advisories/GHSA-7hm3-wp5q-ccv9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48778"},{"type":"FIX","url":"https://github.com/notepad-plus-plus/notepad-plus-plus/commit/24c7b5c63cece76dbc8c4f2607a27ebfe22fa614"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/notepad-plus-plus/notepad-plus-plus","events":[{"introduced":"0"},{"fixed":"41dd976310db0ba551bb8a2810b60331df3a77f5"},{"fixed":"24c7b5c63cece76dbc8c4f2607a27ebfe22fa614"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:notepad-plus-plus:notepad\\+\\+:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"8.9.6.1"}]}}],"versions":["v8.9.6","v8.9.5","v8.9.4","v8.9.3","v8.9.2","v8.9.1","v8.9","v8.8.9","v8.8.8","v8.8.7","v8.8.6","v8.8.5","v8.8.4","v8.8.3","v8.8.2","v8.8.1","v8.8","v8.7.9","v8.7.8","v8.7.7","v8.7.6","v8.7.5","v8.7.4","v8.7.3","v8.7.2","v8.7.1","v8.7","v8.6.9","v8.6.8","v8.6.7","v8.6.6","v8.6.5","v8.6.4","v8.6.3","v8.6.2","v8.6.1","v8.6","v8.5.8","v8.5.7","v8.5.6","v8.5.5","v8.5.4","v8.5.3","v8.5.2","v8.5.1","v8.5","v8.4.9","v8.4.8","v8.4.7","v8.4.6","v8.4.5","v8.4.4","v8.4.3","v8.4.2","v8.4.1","v8.4","v8.3.3","v8.3.2","v8.3.1","v8.3","v8.2.1","v8.2","v8.1.9.3","v8.1.9.2","v8.1.9.1","v8.1.9","v8.1.8","v8.1.7","v8.1.6","v8.1.5","v8.1.4","v8.1.3","v8.1.2","v8.1.1","v8.1","v8","v7.9.5","v7.9.4","v7.9.3","v7.9.2","v7.9.1","v7.9","v7.8.9","v7.8.8","v7.8.7","v7.8.6","v7.8.5","v7.8.4","v7.8.3","v7.8.2","v7.8.1","v7.8","v7.7.1","v7.7","v7.6.6","v7.6.5","v7.6.4","v7.6.3","v7.6.2","v7.6.1","v7.6","v7.5.9","v7.5.8","v7.5.7","v7.5.6","v7.5.5","v7.5.4","v7.5.3","v7.5.2","v7.5.1","v7.4.2","v7.4.1","v7.4","v7.3.3","v7.3.2","v7.3.1","7.3.1","v7.3","v7.2.2","7.2.2","v7.2.1","v7.2","v7.1","v7","v6.9.2","v6.9.1","v6.9","v6.8.9","v6.8.8","v6.8.7","v6.8.6","v6.8.5","v6.8.4","v6.8.3","v6.8.2","v6.8.1","v6.8","v6.7.9.2","v6.7.9.1","v6.7.9","v6.7.8.2","v6.7.8.1","v6.7.8","v6.7.7","v6.7.5","v6.7.4_-_Je_suis_Charlie_edition","v6.7.3","v6.7.2","v6.7.1","v6.7","v6.6.9","v6.6.8","v6.6.7","v6.6.6_-_Friday_the_13th_edition","v6.6.4","v6.6.3","v6.6.2","v6.6.1","v6.6","v6.5.5","v6.5.4","v6.5.3","v6.5.2","v6.5.1","v6.5","v6.4.5","v6.4.4","v6.4.3","v6.4.2","v6.4.1","v6.4","v6.3.3","v6.3.2","v6.3.1","v6.3","v6.2.3_-_End_of_World_Edition","v6.2.2","v6.2.1","v6.2","v6.1.8","v6.1.7","v6.1.6","v6.1.5","v6.1.4","v6.1.3","v6.1.2","v6.1.1","v6.1","v6","v5.9.8","v5.9.7","v5.9.6.2","v5.9.6.1","v5.9.6","v5.9.5","v5.9.4","v5.9.3","v5.9.2","v5.9.1","v5.9","v5.8.7","v5.8.6","v5.8.5","v5.8.4","v5.8.3","v5.8.2","v5.8.1","v5.8","v5.7","v5.6.8","v5.6.7","v5.6.6","v5.6.5","v5.6.4","v5.6.3","v5.6.2","v5.6.1","v5.6","v5.5.1","v5.5","v5.4.5","v5.4.4","v5.4.3","v5.4.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-48778.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
