  • Subject: [VULNERABILITY ALERT] MongoDB Contains High-Risk Security Vulnerability (CVE-2025-14847), Please Verify and Patch Immediately


  • Content Description:
    • Forwarded from National Information Security Information Sharing and Analysis Center Security Alert NISAC-200-202601-00000030
    • Researchers have discovered an Improper Handling of Length Parameter Inconsistency vulnerability (CVE-2025-14847) in MongoDB.
    • An unauthenticated remote attacker can send specially crafted zlib-compressed communication packets to trigger an issue where the system fails to properly validate parameter lengths when processing decompressed data. This can lead to reading uninitialized memory contents during the document parsing process, resulting in sensitive information leakage. This vulnerability has already been exploited by hackers; please verify and patch as soon as possible.
