SCA: security update for langsmith (GHSA-v34v-rq6j-cj6p)
medium Tenable Self-Hosted Container Security Plugin ID 437670
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- LangSmith Client SDKs provide SDK's for interacting with the LangSmith platform. The LangSmith SDK's
distributed tracing feature is vulnerable to Server-Side Request Forgery via malicious HTTP headers. An
attacker can inject arbitrary api_url values through the baggage header, causing the SDK to exfiltrate
sensitive trace data to attacker-controlled endpoints. When using distributed tracing, the SDK parses
incoming HTTP headers via RunTree.from_headers() in Python or RunTree.fromHeaders() in Typescript. The
baggage header can contain replica configurations including api_url and api_key fields. Prior to the fix,
these attacker-controlled values were accepted without validation. When a traced operation completes, the
SDK's post() and patch() methods send run data to all configured replica URLs, including any injected by
an attacker. This vulnerability is fixed in version 0.6.3 of the Python SDK and 0.4.6 of the JavaScript
SDK. (CVE-2026-25528)
