+## PDSA-2022-002: Code injection in paddle.audio.functional.get_window
+
+### Impact
+
+`paddle.audio.functional.get_windowis` vulnerable to a code injection as it calls `eval` on user supplied `winstr`. This may lead to arbitrary code execution.
+
+```python
+def get_window(
+    window: Union[str, Tuple[str, float]],
+    win_length: int,
+    fftbins: bool = True,
+    dtype: str = 'float64',
+) -> Tensor:
+    ...
+    try:
+        winfunc = eval('_' + winstr)
+    except NameError as e:
+        raise ValueError("Unknown window type.") from e
+```
+
+### Patches
+
+We have patched the issue in commit [26c419ca386aeae3c461faf2b828d00b48e908eb](https://github.com/PaddlePaddle/Paddle/commit/26c419ca386aeae3c461faf2b828d00b48e908eb).
+
+The fix will be included in PaddlePaddle 2.4.
+
+### For more information

+## PDSA-2022-002: Code injection in paddle.audio.functional.get_window
+
+### 影响
+
+`paddle.audio.functional.get_window`由于使用`eval`用户提供的参数`winstr`而存在代码注入漏洞，将导致任意代码执行。
+
+```python
+def get_window(
+    window: Union[str, Tuple[str, float]],
+    win_length: int,
+    fftbins: bool = True,
+    dtype: str = 'float64',
+) -> Tensor:
+    ...
+    try:
+        winfunc = eval('_' + winstr)
+    except NameError as e:
+        raise ValueError("Unknown window type.") from e
+```
+
+### 补丁
+
+我们在commit [26c419ca386aeae3c461faf2b828d00b48e908eb](https://github.com/PaddlePaddle/Paddle/commit/26c419ca386aeae3c461faf2b828d00b48e908eb)中对此问题进行了补丁。
+
+修复将包含在飞桨2.4版本当中。
