CVE-2026-34444

Scoder Lupa broken access control

10.0 CRITICALPublic exploitEPSS 0.80%
  1. Published6 Apr 2026

Description

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.
