A vulnerability in langchain-core versions >=0.1.17,=0.2.0,=0.3.0,<0.3.15 allows unauthorized users to read arbitrary files from the host file system.

If the outputs of these prompt templates are exposed to the user, either directly or through downstream model outputs, it can lead to the exposure of sensitive information.
