Mitigation Strategies

To mitigate this vulnerability, the key step is to apply the security fix that disables the loading of Lua bytecode in the f_parser() function within the perf-ninja project.

This fix prevents exploitation of the code injection vulnerability by eliminating the ability to load potentially malicious Lua bytecode.

Ensure your perf-ninja installation is updated to include the patch merged on June 15, 2025, which addresses this issue.
