Researchers have discovered an Improper Handling of Length Parameter Inconsistency vulnerability (CVE-2025-14847) in MongoDB. An unauthenticated remote attacker can exploit this vulnerability by sending specially crafted zlib-compressed communication packets. When the system processes the decompressed data, it fails to properly validate parameter lengths, which may result in reading uninitialized memory during the document parsing process, leading to the disclosure of sensitive information. This vulnerability has already been exploited by attackers. Please promptly verify and apply the necessary fixes.
