Detailsinfo

A vulnerability was found in zopefoundation RestrictedPython up to 7.x. It has been declared as problematic. This vulnerability affects an unknown functionality. The manipulation with an unknown input leads to a type confusion vulnerability. The CWE definition for the vulnerability is CWE-843. The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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 advisory is available at github.com. This vulnerability was named CVE-2025-22153 since 12/30/2024. The exploitation appears to be difficult. The attack can be initiated remotely. Additional levels of successful authentication are required for exploitation. The technical details are unknown and an exploit is not available.
