SCA: security update for RestrictedPython (GHSA-hp3v-5vw7-fx9w)

high Tenable Self-Hosted Container Security Plugin ID 448153

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - RestrictedPython is a tool that helps define a subset of the Python language for accepting program input
 in a trusted environment. Prior to 8.4, RestrictedPython could allow a sandbox escape when a custom import
 policy or globals exposed the standard library string module, the string.Formatter class, a Formatter
 instance, or a Formatter subclass to restricted code. The string.Formatter methods format, get_field,
 get_value, and vformat performed attribute and item traversal internally without passing through
 RestrictedPython's safer_getattr protections. Restricted code could use those live object references to
 reach function globals, builtins, file access, or code execution primitives, affecting confidentiality,
 integrity, and availability in the host environment. This issue is fixed in version 8.4. (CVE-2026-76825)

Solution

Update the RestrictedPython library and its related packages to version 8.4 or later.
