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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H","score":6.7},"cwes":["CWE-78","CWE-345","CWE-693"],"references":["https://github.com/notepad-plus-plus/notepad-plus-plus/commit/4cd74cb9347b9c6caaab17d999e24fc9ed228ff7","https://github.com/notepad-plus-plus/notepad-plus-plus/releases/tag/v8.9.8","https://github.com/notepad-plus-plus/notepad-plus-plus/security/advisories/GHSA-759j-g8j4-867p","https://notepad-plus-plus.org/news/v898-released","https://github.com/notepad-plus-plus/notepad-plus-plus/security/advisories/GHSA-759j-g8j4-867p"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-85288","score":0.00136,"percentile":0.0299,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
