Does this matter?

Lower severity and a low EPSS score (0.15%). Track it; it rarely justifies an emergency change on its own.

Description

Out-of-bounds Read vulnerability in dail8859 NotepadNext (src/lua/src modules). This vulnerability is associated with program files lparser.C. This issue affects NotepadNext: through v0.11. The singlevar() in lparser.c lacks a certain luaK_exp2anyregup call, leading to a heap-based buffer over-read that might affect a system that compiles untrusted Lua code.
