GHSA-M8J6-RC5X-WV36 nono-py's policy JSON accepts unknown security fields

Summary nono-py policy handling could fail open in two ways. First, resolving a policy-derived ProxyConfig did not automatically enforce CapabilitySet.proxyonly, allowing sandboxed children to bypass a resolved domain allowlist by using direct network access. Second, policy JSON accepted unknown...

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...

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-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...

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...

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...

Interpretation Conflict

Overview Affected versions of this package are vulnerable to Interpretation Conflict via the downloadImage process. An attacker can execute arbitrary scripts in the context of the application by tricking a user into visiting a crafted link that proxies malicious content through the image proxy...

GHSA-4C8J-MGM4-QQVP Remark42: Cross-Site Scripting (XSS) on /api/v1/img via content-type spoofing

Summary The remark42 image proxy fetches an arbitrary remote URL and re-serves the response from remark42's own origin. The download path decides whether the fetched resource is an image by looking only at the Content-Type header the remote server claims — it never inspects the actual bytes. The...
