CVE-2026-34444
criticalLupa integrates the runtimes of Lua or LuaJIT2 into CPython.
Vendor / product: Scoder — lupa
Lupa integrates the runtimes of Lua or LuaJIT2 into CPython. In 2.6 and earlier, attribute_filter is not consistently applied when attributes are accessed through built-in functions like getattr and setattr. This allows an attacker to bypass the intended restrictions and eventually achieve arbitrary code execution.
