CVE-2022-45908Network attack vector

Arbitrary code execution via evaluated window name

Published Nov 26, 2022 · Updated Apr 25, 2025

Code injection in PaddlePaddle before 2.4 allows attackers to execute arbitrary code through a crafted audio-window name. The paddle.audio.functional.get_window function prefixes winstr with an underscore and passes the result to Python eval without restricting it to registered window functions. The affected application must pass attacker-controlled winstr data into the function, and execution occurs with the hosting process privileges.
