CVE-2024-47532: RestrictedPython information leakage via `AttributeError.obj` and the `string` module
First published: Mon Sep 30 2024(Updated: )
### Impact A user can gain access to protected (and potentially sensible) information indirectly via `AttributeError.obj` and the `string` module. ### Patches The problem will be fixed in version 7.3. ### Workarounds If the application does not require access to the module `string`, it can remove it from `RestrictedPython.Utilities.utility_builtins` or otherwise do not make it available in the restricted execution environment.
