The `key` and `value` parameters accept arbitrarily large inputs without proper validation, leading to a null pointer error in the Rust-based backend when excessively large values are submitted. This results in the inability to create new memories, impacting the stability of the service."}], "lastModified": "2025-10-31T00:15:37.480", "sourceIdentifier": "security@huntr.dev"}
