Sensitive Data Exposure

Reachability: Internal
Exploitability: Difficult
CWE: CWE-532 — Insertion of Sensitive Information into Log File

Sanitize 7z failures before plugin logging.

execute_multi_line_cmd(cmd_list) raises CalledProcessError with the original command string. The plugin handler logs that exception, so a failed 7z command can expose the password. Catch the failure and raise an exception with only the return code. Use from None to suppress the original traceback.

Sanitize the failure exception 
         import shlex
+        import subprocess
...
-        self.execute_multi_line_cmd(cmd_list)
+        try:
+            self.execute_multi_line_cmd(cmd_list)
+        except subprocess.CalledProcessError as error:
+            raise RuntimeError(
+                f'7z执行失败，返回码: {error.returncode}'
+            ) from None

Review comment at @src/jmcomic/jm_plugin.py at line 1434:
7z failures can expose the password when the plugin logs the original
CalledProcessError. In the method containing execute_multi_line_cmd, catch
subprocess.CalledProcessError and raise an exception containing only its return
code, using from None to suppress the original traceback.
