Note

Medium Risk
Dependency-only change, but it upgrades the LangChain/OpenAI dependency graph and could alter AI/workflow-builder runtime behavior (and includes security-related upstream changes like SSRF hardening).

Overview
Updates the workspace dependency catalog to bump @langchain/community from 1.0.5 to 1.1.18.

Regenerates pnpm-lock.yaml accordingly, which updates a large set of transitive LangChain-related packages (notably introducing newer @langchain/classic, @langchain/openai, and openai@6.22.0 entries) and normalizes some axios resolutions that previously included a debug sub-resolution.

@langchain/core peer dependency version mismatch

Medium Severity

@langchain/community 1.1.18 declares a peer dependency on @langchain/core ^1.1.27, but the workspace catalog pins @langchain/core at 1.1.8. Version 1.1.8 does not satisfy ^1.1.27 (>=1.1.27), which can trigger peer dependency warnings and possible runtime issues if the community package relies on APIs added in 1.1.27.

Optional deps mismatch for CSV, PDF, HuggingFace

Medium Severity

The @langchain/community@1.1.18(26fe6969...) variant in the lockfile pins optional deps that no longer satisfy the package’s peer deps: @huggingface/inference 4.0.5 (peer ^4.13.12), d3-dsv 2.0.0 (peer ^3.0.1), and pdf-parse 1.1.1 (peer 2.4.5). CSVLoader, PDFLoader, and HuggingFace integrations may fail or behave incorrectly when these older versions are used.
