CyberRota Analysis

AI-Generated

Notepad++ versions prior to 8.9.7 are vulnerable due to improper validation of the backupFilePath attribute, which allows attackers to exploit parent-directory sequences and access arbitrary files outside the designated backup directory during snapshot-mode restoration. This could lead to unauthorized exposure of sensitive user-readable files. Users and organizations utilizing Notepad++ for code editing should prioritize updating to version 8.9.7 to mitigate this risk.

Original NVD Description

Notepad++ is a free and open-source source code editor. Prior to 8.9.7, Notepad++ validates the backupFilePath attribute from session.xml with std::wstring::starts_with against the expected backup directory without path normalization, allowing parent-directory sequences during snapshot-mode restoration to read an arbitrary user-readable file outside the backup directory into an editor tab. This issue is fixed in version 8.9.7.
