Description
Impact
Via a type confusion bug in the CPython interpreter when using try/except* RestrictedPython could be bypassed.
We believe this should be fixed upstream in Python itself until that we remove support for try/except* from RestrictedPython.
(It has been fixed for some Python versions.)
Patches
Patched in version 8.0 by removing support for try/except* clauses
Workarounds
There is no workaround.
