Summary
try/except* clauses could allow bypass RestrictedPython via type confusion bug in the CPython interpreter
Details

RestrictedPython is a tool that helps to define a subset of the Python language which allows to provide a program input into a trusted environment. Via a type confusion bug in versions of the CPython interpreter starting in 3.11 and prior to 3.13.2 when using try/except*, RestrictedPython starting in version 6.0 and prior to version 8.0 could be bypassed. The issue is patched in version 8.0 of RestrictedPython by removing support for try/except* clauses. No known workarounds are available.
