Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Information Disclosure: Secrets printed during container execution or streamed via multi-write operations could bypass scrubbing layers due to trie-splitting bugs or multi-write fragmentation. Stream transformer-based readers and line-by-line validation were required to resolve this.
Auth Bypass: Inadequate cryptographic scoping allowed cross-client exposure of socket connections and secrets. This required introducing HMAC-based per-client isolation to securely gate tunnels.
Path Traversal: Path traversal during changeset exports and workspace interactions allowed arbitrary file actions or escape beyond module context roots on both Windows and Linux clients.
