Severity ?

7.9 (High) - CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:L

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.

Severity ?

7.9 (High) - CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:L

Summary

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.
