Name of the Vulnerable Software and Affected Versions Lupa versions 2.6 and earlier

Description Lupa integrates the runtimes of Lua or LuaJIT2 into CPython. In versions 2.6 and earlier, the attribute filter is not consistently applied when attributes are accessed through built-in functions like getattr and setattr. This allows an attacker to bypass intended restrictions and potentially achieve arbitrary code execution.

Recommendations Update to a version of Lupa later than 2.6.
