Arbitrary file read via prompt path input
Published Mar 20, 2025 · Updated Mar 20, 2025
Arbitrary file read in affected LangChain Core releases allows remote attackers to read host files through prompt path input. The ImagePromptTemplate format method accepted a user-controlled path and passed it to image_to_data_url, whose encode_image helper opened and Base64-encoded that file. Exposure requires an application to let attackers control the prompt path and return the template output directly or through downstream model output.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
