CVE-2024-28088: LangChain through 0.1.10 allows ../ directory traversal by an actor who is able to control the final part of the path parameter in a load_ch

Noroxi assessment

Priority: Monitor (action score 33/100)

Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 1.7% (FIRST EPSS); higher than 77.8% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: langchain (PyPI) 0.0.339, 0.1.11; langchain-core (PyPI) 0.1.30, 0.1.11.

Low priority for now. Upgrade to langchain (PyPI) 0.0.339, 0.1.11; langchain-core (PyPI) 0.1.30, 0.1.11 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

LangChain through 0.1.10 allows ../ directory traversal by an actor who is able to control the final part of the path parameter in a load_chain call. This bypasses the intended behavior of loading configurations only from the hwchase17/langchain-hub GitHub repository. The outcome can be disclosure of an API key for a large language model online service, or remote code execution. (A patch is available as of release 0.1.29 of langchain-core.)

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.
