Access Control Bypass

Overview nono-py is a Python bindings for nono capability-based sandboxing Affected versions of this package are vulnerable to Access Control Bypass due to the policy JSON accepting unknown security-sensitive fields and the failure to automatically enforce CapabilitySet.proxyonly when resolving a...

GHSA-9J7F-3R4P-PWH6 nono-py vulnerable to authorization bypass / policy confusion

The python API made a restrictive-looking configuration unsafe by default. A caller could configure only reverse- proxy credential routes, put the child in CapabilitySet.proxyonly, and reasonably expect network access to be limited to those routes. Instead, because empty allowedhosts meant...

Insecure Default Initialization of Resource

Overview nono-py is a Python bindings for nono capability-based sandboxing Affected versions of this package are vulnerable to Insecure Default Initialization of Resource due to improper enforcement of access restrictions in the proxy process. An attacker can gain unauthorized network access by...

GHSA-72W7-MF9G-733P nono-py has proxy-only network fallback bypass on older Linux kernels

Summary On Linux kernels that do not support Landlock network rules, nonopy.sandboxedexec could run CapabilitySet.proxyonlyproxy without supervising the seccomp-notify proxy-only fallback returned by the Rust core. In that configuration, a sandboxed child process could remove HTTPPROXY / HTTPSPRO...

Protection Mechanism Failure

Overview nono-py is a Python bindings for nono capability-based sandboxing Affected versions of this package are vulnerable to Protection Mechanism Failure in the sandboxedexec process when running on Linux kernels lacking Landlock network support. An attacker can access sensitive network resourc...

PT-2026-56101

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...
