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.

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7355-1 advisory.

    Nakul Choudhary and Robert Xiao discovered that RestrictedPython did not properly sanitize certain inputs.
    An attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 20.04     LTS and Ubuntu 22.04 LTS. (CVE-2023-37271)

    Abhishek Govindarasu, Ankush Menat and Ward Theunisse discovered that RestrictedPython did not correctly     handle certain format strings. An attacker could possibly use this issue to leak sensitive information.
    This issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2023-41039)

    It was discovered that RestrictedPython did not correctly restrict access to certain fields. An attacker     could possibly use this issue to leak sensitive information. (CVE-2024-47532)

    It was discovered that RestrictedPython contained a type confusion vulnerability. An attacker could     possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and Ubuntu     24.10. (CVE-2025-22153)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
