      <title>CVE-2025-22153 — try/except* clauses could allow bypass RestrictedPython via type confusion bug in the CPython interpreter</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2025-22153</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; zopefoundation RestrictedPython&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;</description>

      <title>GHSA-gmj9-h825-chq2 — try/except* clauses could allow bypass RestrictedPython via type confusion bug in the CPython interpreter</title>
      <link>https://cve.radiocsirt.org/vuln/ghsa-gmj9-h825-chq2</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; PyPI: RestrictedPython&lt;/p&gt;
&lt;p&gt;### Impact
Via a type confusion bug in the CPython interpreter when using `try/except*` RestrictedPython could be bypassed.&lt;/p&gt;
&lt;p&gt;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.)&lt;/p&gt;
&lt;p&gt;### Patches
Patched in version 8.0 by removing support for `try/except*` clauses&lt;/p&gt;
&lt;p&gt;### Workarounds
There is no workaround.&lt;/p&gt;
&lt;p&gt;### References
none&lt;/p&gt;</description>
