GHSA-9J7F-3R4P-PWH6 is a medium-severity security vulnerability in nono-py (pip), affecting versions <= 0.10.1. It is fixed in 0.11.0.
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 allow-all inside nono-proxy, the child could use the local proxy as a transparent CONNECT tunnel to non-route nominated hosts (not including metadata endpoints). That is an authorization bypass / policy confusion issue: Intended policy: route-only proxy access. Actual policy: route-only plus arbitrary transparent CONNECT. Boundary crossed: sandboxed child gains broader outbound network reach than the Python policy appears to grant. Impact depends on environment, but it can allow exfiltration or access to unintended internet/internal services through the unsandboxed proxy. This should be classified as medium severity by default, potentially high if users rely on route-only configs for strict egress control around untrusted code or sensitive credentials. The fix is security-relevant because it changes the default from implicit allow-all to explicit opt-in.
GHSA-9J7F-3R4P-PWH6 has a CVSS score of 5.2 (Medium). The vector is requires local access, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment.
A fixed version is available (0.11.0). Upgrading removes the vulnerable code path.
pip
nono-py (<= 0.10.1)nono-py → 0.11.0 (pip)Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.
Kodem's runtime-powered SCA identifies whether GHSA-9J7F-3R4P-PWH6 is reachable in your applications. Explore open-source security for your team.

GHSA-9J7F-3R4P-PWH6 has a CVSS score of 5.2 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
nono-py (pip) versions <= 0.10.1 is affected.
Yes. GHSA-9J7F-3R4P-PWH6 is fixed in 0.11.0. Upgrade to this version or later.
Whether GHSA-9J7F-3R4P-PWH6 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
Upgrade nono-py to 0.11.0 or later.
