Prior to versions 0.3.81 and 1.2.5, a serialization injection vulnerability exists in LangChain&#39;s dumps() and dumpd() functions. The functions do not escape dictionaries with &#39;lc&#39; keys when serializing free-form dictionaries. The &#39;lc&#39; key is used internally by LangChain to mark serialized objects. When user-controlled data contains this key structure, it is treated as a legitimate LangChain object during deserialization rather than plain user data. This issue has been patched in versions 0.3.81 and 1.2.5.</p> <p><strong>Affected:</strong> langchain-ai langchain</p> <p>LangChain is a framework for building agents and LLM-powered applications.
