How to Fix GHSA-m8j6-rc5x-wv36

To remediate this vulnerability, upgrade all affected Nono py dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

nono-py fixed: 0.10.1 
pip install nono-py>=0.10.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show nono-py

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-m8j6-rc5x-wv36, inspect your installed packages using pip:

pip show nono-py

Analyze the terminal output to locate any version of Nono py in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.10.1), your application is affected.

Note: The pip show nono-py command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Nono py, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary nono-py policy handling could fail open in two ways. First, resolving a policy-derived `ProxyConfig` did not automatically enforce `CapabilitySet.proxy_only`, allowing sandboxed children to bypass a resolved domain allowlist by using direct network access. Second, policy JSON accepted unknown security-sensitive fields, so misspelled or unsupported restrictions could be silently ignored. ### Impact A sandboxed child may receive broader network access than the policy author intended. This can allow outbound requests outside the configured proxy allowlist and may expose sensitive data depending on the execution environment and workload. ### Older-kernel note On Linux kernels without Landlock ABI v4 network rules, patched versions continue to support proxy-only enforcement through the seccomp supervisor fallback introduced in 807fb4b. Users on older kernels should ensure policy-resolved proxy configurations are coupled to `CapabilitySet.proxy_only(proxy);` merely injecting proxy environment variables is not sufficient.
