It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-146 advisory.
singlevar in lparser.c in Lua from (including) 5.4.0 up to (excluding) 5.4.4 lacks a certain luaK_exp2anyregup call, leading to a heap-based buffer over-read that might affect a system that compiles untrusted Lua code. (CVE-2022-28805)
An issue in the component luaG_runerror of Lua v5.4.4 and below leads to a heap-buffer overflow when a recursive error occurs. (CVE-2022-33099)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
