Lupa
Monthly
Arbitrary code execution in Lupa (Python-Lua integration library) versions ≤2.6 allows unauthenticated remote attackers to bypass attribute filtering controls via Python's getattr/setattr built-ins. The vulnerability enables attackers to circumvent sandbox restrictions designed to limit Lua runtime access to sensitive Python objects, ultimately achieving code execution in the CPython host process. EPSS data unavailable; no CISA KEV listing or public exploit identified at time of analysis, though exploitation complexity is low per CVSS vector (AC:L, PR:N).
