Doc Text:
A flaw was found in Locutus, a JavaScript library that provides standard library functions. The `create_function` function in Locutus passes user-supplied arguments and code directly to the JavaScript `Function` constructor without proper sanitization. This vulnerability allows a remote attacker to execute arbitrary code within the application, potentially leading to full system compromise or data manipulation.

Description OSIDB Bzimport 2026-03-12 22:02:10 UTC
Locutus brings stdlibs of other programming languages to JavaScript for educational purposes. Prior to 3.0.14, the create_function(args, code) function passes both parameters directly to the Function constructor without any sanitization, allowing arbitrary code execution. This is distinct from CVE-2026-29091 which was call_user_func_array using eval() in v2.x. This finding affects create_function using new Function() in v3.x. This vulnerability is fixed in 3.0.14.
