CyberRota Analysis
AI-GeneratedNotepad++ versions prior to 8.9.8 are vulnerable to a stack buffer overflow due to improper handling of plugin-supplied lexer counts, which can lead to arbitrary code execution. This vulnerability allows a malicious plugin to overwrite stack memory, potentially compromising the integrity of the Notepad++ process. Organizations using Notepad++ should prioritize upgrading to version 8.9.8 to mitigate this high-severity risk.

Original NVD Description
Notepad++ is a free and open-source source code editor. Prior to 8.9.8, Notepad++ contains a stack buffer overflow in PluginsManager::loadPluginFromPath in PowerEditor/src/MISC/PluginsManager/PluginsManager.cpp because the plugin-supplied GetLexerCount() result controls a loop that writes to containers[30] without enforcing NB_MAX_EXTERNAL_LANG. A malicious or compromised plugin that reports more than 30 lexers can write beyond the stack array and corrupt control data, which can permit arbitrary code execution in the Notepad++ process context. This issue is fixed in version 8.9.8.
