Eugene Yurtsev	e8339b1d83	core[patch]: Patch XML vulnerability in XMLOutputParser (CVE-2024-1455) (#19653 ) Patch potential XML vulnerability CVE-2024-1455 This patches a potential XML vulnerability in the XMLOutputParser in langchain-core. The vulnerability in some situations could lead to a denial of service attack. At risk are users that: 1) Running older distributions of python that have older version of libexpat 2) Are using XMLOutputParser with an agent 3) Accept inputs from untrusted sources with this agent (e.g., endpoint on the web that allows an untrusted user to interact wiith the parser)	5 months ago

mwmajewsk	f7a1fd91b8	community: better support of pathlib paths in document loaders (#18396 ) So this arose from the https://github.com/langchain-ai/langchain/pull/18397 problem of document loaders not supporting `pathlib.Path`. This pull request provides more uniform support for Path as an argument. The core ideas for this upgrade: - if there is a local file path used as an argument, it should be supported as `pathlib.Path` - if there are some external calls that may or may not support Pathlib, the argument is immidiately converted to `str` - if there `self.file_path` is used in a way that it allows for it to stay pathlib without conversion, is is only converted for the metadata.

Yuki Watanabe	cfecbda48b	community[minor]: Allow passing `allow_dangerous_deserialization` when loading LLM chain (#18894 ) ### Issue Recently, the new `allow_dangerous_deserialization` flag was introduced for preventing unsafe model deserialization that relies on pickle without user's notice (#18696). Since then some LLMs like Databricks requires passing in this flag with true to instantiate the model. However, this breaks existing functionality to loading such LLMs within a chain using `load_chain` method, because the underlying loader function [load_llm_from_config](`f96dd57501/libs/langchain/langchain/chains/loading.py (L40)`) (and load_llm) ignores keyword arguments passed in. ### Solution This PR fixes this issue by propagating the `allow_dangerous_deserialization` argument to the class loader iff the LLM class has that field. --------- Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com> Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com>	5 months ago

Shotaro Sano	55c624a694	infra: Resolve the endless dependency resolution during the build of `dev.Dockerfile` by copying `poetry.lock` (#19465 ) ## Description This PR proposes a modification to the `libs/langchain/dev.Dockerfile` configuration to copy the `libs/langchain/poetry.lock` into the working directory. The change aims to address the issue where the Poetry install command, the last command in the `dev.Dockerfile`, takes excessively long hours, and to ensure the reproducibility of the poetry environment in the devcontainer. ## Problem The `dev.Dockerfile`, prepared for development environments such as `.devcontainer`, encounters an unending dependency resolution when attempting the Poetry installation. ### Steps to Reproduce Execute the following build command: ```bash docker build -f libs/langchain/dev.Dockerfile . ``` ### Current Behavior The Docker build process gets stuck at the following step, which, in my experience, did not conclude even after an entire night: ``` => [langchain-dev-dependencies 4/6] COPY libs/community/ ../community/ 0.9s => [langchain-dev-dependencies 5/6] COPY libs/text-splitters/ ../text-splitters/ 0.0s => [langchain-dev-dependencies 6/6] RUN poetry install --no-interaction --no-ansi --with dev,test,docs 12.3s => => # Updating dependencies => => # Resolving dependencies... ``` ### Expected Behavior The Docker build completes in a realistic timeframe. By applying this PR, the build finishes within a few minutes. ### Analysis The complexity of LangChain's dependencies has reached a point where Poetry is required to resolve dependencies akin to threading a needle. Consequently, poetry install fails to complete in a practical timeframe. ## Solution The solution for dependency resolution is already recorded in `libs/langchain/poetry.lock`, so we can use it. When copying `project.toml` and `poetry.toml`, the `poetry.lock` located in the same directory should also be copied. ```diff # Copy only the dependency files for installation -COPY libs/langchain/pyproject.toml libs/langchain/poetry.toml ./ +COPY libs/langchain/pyproject.toml libs/langchain/poetry.toml libs/langchain/poetry.lock ./ ``` ## Note I am not intimately familiar with the historical context of the `dev.Dockerfile` and thus do not know why `poetry.lock` has not been copied until now. It might have been an oversight, or perhaps dependency resolution used to complete quickly even without the `poetry.lock` file in the past. However, if there are deliberate reasons why copying `poetry.lock` is not advisable, please just close this PR.	5 months ago
