About this tag
The lua security tag covers vulnerabilities and patch guidance for the Lua scripting language, particularly heap-based buffer over-read flaws in the Lua parser (lparser.c). Discussions include CVE-2026-24821 affecting WickedEngine's Lua parsing code and CVE-2022-28805 affecting Lua 5.4.x, both of which can be triggered by untrusted Lua scripts. The tag provides practical patch guides for developers and system administrators who embed Lua in applications, games, or enterprise software. Topics focus on identifying affected versions, applying upstream fixes, and mitigating risks from malicious Lua input. Security updates, parser internals, and remediation steps are recurring themes.
