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

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.

References

none

Severity ?
7.9 (High)
