gate0

gate0 A small, auditable, terminating, deterministic micro-policy engine. Why Gate0? I built Gate0 because I was tired of debugging RegEx-based policies in production. I wanted something that was boring, bounded, and impossible to crash. If you want a flexible, general-purpose policy engine, you...

CVE-2026-78427

The NeuVector admission webhook silently excludes containers from policy evaluation when their image path matches one of three hardcoded service mesh sidecar images. Since the image path is entirely controlled by the workload author, any user capable of deploying workloads can evade admission den...

Gotenberg <= 8.30.1 - Server Side Request Forgery

Gotenberg is an API-based document conversion tool. In versions 8.30.1 and earlier, the default private-IP deny-lists for the --webhook-deny-list and --api-download-from-deny-list flags use a case-sensitive regular expression ^https?:// to match URL schemes. Because Go's net/url.Parse normalizes...

rsync: rsync: Authorization bypass via `auth users` directive parsing

An authorization bypass flaw was found in the rsync daemon. The auth users directive parser incorrectly handles group names containing spaces due to comma-only tokenization. This flaw causes deny rules to be silently discarded, allowing an authenticated user to bypass restrictions and gain...

rsync: rsync 3.1.0 < 3.5.0 Access Control Bypass via DNS Resolution Failure

A flaw was found in rsync. This vulnerability allows a remote attacker to bypass hostname-based access control rules. By inducing DNS resolution failures, the rsync daemon incorrectly skips deny rules, granting unauthorized access to restricted module file trees...
