Echo: langsmith: security update to 0.5.19

medium Tenable Self-Hosted Container Security Plugin ID 461778

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. Prior to version 0.5.19
of the JavaScript SDK and version 0.7.31 of the Python SDK, the LangSmith SDK's output redaction controls
(hideOutputs in JS, hide_outputs in Python) do not apply to streaming token events. When an LLM run
produces streaming output, each chunk is recorded as a new_token event containing the raw token value.
These events bypass the redaction pipeline entirely — prepareRunCreateOrUpdateInputs (JS) and
_hide_run_outputs (Python) only process the inputs and outputs fields on a run, never the events array. As
a result, applications relying on output redaction to prevent sensitive LLM output from being stored in
LangSmith will still leak the full streamed content via run events. Version 0.5.19 of the JavaScript SDK
and version 0.7.31 of the Python SDK fix the issue. (CVE-2026-41182)

Solution

Update the langsmith library and its related packages to version 0.5.19 or later.
