CVE-2026-7597 Details
Description
A vulnerability was found in mem0ai mem0 up to 1.0.11. This affects the function pickle.load/pickle.dump of the file mem0/vector_stores/faiss.py. Performing a manipulation results in deserialization. It is possible to initiate the attack remotely. The exploit has been made public and could be used. The patch is named 62dca096f9236010ca15fea9ba369ba740b86b7a. Applying a patch is the recommended action to fix this issue.
A remote code execution vulnerability exists in Mem0 versions through 1.0.11, specifically within the FAISS vector store implementation. The issue arises from unsafe deserialization of data using Python's pickle module, which can be exploited to execute arbitrary commands on the server. This vulnerability is particularly concerning as it allows attackers to manipulate FAISS index files, potentially poisoning search results or executing malicious payloads that could compromise the server.
Users are advised to update to Mem0 version 1.0.12 or later, where this vulnerability has been fixed. The update process involves applying the patch available in the official Mem0 repository.
