CVE-2026-76825
NVD: RestrictedPython is a tool that helps define a subset of the Python language for accepting program input in a trusted environment. NVD: Prior to 8.4, RestrictedPython could allow a sandbox escape when a custom import policy or globals exposed the standard library string module, the string.Formatter class, a Formatter instance, or a Formatter subclass to restricted code. NVD: The string.Formatter methods format, get_field, get_value, and vformat performed attribute and item traversal internally without passing through RestrictedPython's safer_getattr protections.
