Name of the Vulnerable Software and Affected Versions: NotepadNext versions through v0.11

Description: The issue is an Out-of-bounds Read vulnerability in the NotepadNext Lua Parser Module, specifically affecting the singlevar() function in lparser.c. This vulnerability can lead to a heap-based buffer over-read, potentially impacting systems that compile untrusted Lua code. The luaK exp2anyregup call is lacking in the singlevar() function, causing this issue.

Recommendations: For versions through v0.11, consider disabling the singlevar() function in lparser.c as a temporary workaround to minimize the risk of exploitation. Restrict access to untrusted Lua code compilation to reduce the potential impact of this issue. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
