The vulnerabilities' rating ranges from medium to high.

But nothing happened, the developer continuously released new Notepad+++ versions without addressing the vulnerabilities.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/i.postimg.cc\/ZRwsC31H\/image.png\" \/><\/p>\n<p>After that, Jaroslav Lobacevski decided to go public and published the details on his <a href=\"https:\/\/securitylab.github.com\/advisories\/GHSL-2023-092_Notepad__\/\" target=\"_blank\" rel=\"noopener\">GitHub security page<\/a> as of August 21, 2023. I had gathered more details about the process and the vulnerabilities in the blog post <a href=\"https:\/\/borncity.com\/win\/2023\/09\/02\/vulnerabilities-in-notepad-sept-2023\/\">Vulnerabilities in Notepad ++ (Sept. 2023)<\/a>.

On the <a href=\"https:\/\/notepad-plus-plus.org\/downloads\/v8.5.7\/\" target=\"_blank\" rel=\"noopener\">download page<\/a>, the notes on fixes that can be seen there state that vulnerabilities CVE-2023-40031, CVE-2023-40036, CVE-2023-40164 and CVE-2023-40166 have been fixed.<\/p>\n<p>In addition, the author writes that he has made another security improvement, in which the uninstaller has now probably also been signed. I also read in the changelog that another possible memory leak when reading Utf8-16 files has been fixed.
