AV:N/AC:L/Au:S/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions mem0ai mem0 versions prior to 1.0.12

Description An unsafe deserialization issue exists in the pickle.load() and pickle.dump() functions within the mem0/vector stores/faiss.py file. This allows a remote attacker to perform a manipulation that results in deserialization, which is the process of converting a byte stream back into an object.

Recommendations Apply patch 62dca096f9236010ca15fea9ba369ba740b86b7a to resolve the issue. As a temporary workaround, restrict the use of the pickle.load() and pickle.dump() functions in the mem0/vector stores/faiss.py file.
