Name of the Vulnerable Software and Affected Versions Notepad++ versions prior to 7.7

Description The issue is related to insufficient input validation in the SciLexer.dll component of the Scintilla text editing component in Notepad++. This can be exploited by a remote attacker using a specially crafted .ml file containing Unicode characters, potentially leading to remote code execution or denial of service.

Recommendations For versions prior to 7.7, update to version 7.7 or later to resolve the issue. As a temporary workaround, consider avoiding the use of .ml files containing Unicode characters in Notepad++ until the update is applied.
