Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: JSON-shaped attachment payloads could bypass filesystem protection checks during serialization, enabling attackers to read and upload arbitrary local files via the client. This is tracked under GHSA-f4xh-w4cj-qxq8.
Mass Assignment: Distributed-tracing baggage headers were vulnerable to parameter injection and arbitrary updates, requiring a strict fail-closed allow-list to ensure only safe replica values are populated.
Insecure Deserialization: LangSmith SDK is vulnerable to insecure deserialization (CVE-2026-45134) when fetching and parsing prompt manifests from external parties, which can allow attackers to hijack runtime execution.
