Introduction
The cybersecurity community has recently been alerted to a high-severity vulnerability in MongoDB, an open-source NoSQL database. This flaw, known as CVE-2025-14847 and rated with a CVSS score of 8.7, poses a significant risk to users who have not yet applied the necessary patches.
Vulnerability Details
The vulnerability arises from improper handling of length parameter inconsistency within MongoDB’s codebase. Specifically, this occurs when a program fails to appropriately manage scenarios where a length field is inconsistent with the expected value. This oversight can lead to unauthorized access to uninitialized heap memory, potentially exposing sensitive data or enabling further attacks.
Implications
The ramifications of exploiting this flaw are severe. Unauthenticated attackers could gain unauthorized access to critical data stored in MongoDB databases. This could result in data breaches, loss of customer information, and significant financial damage for organizations relying on these databases.
Criticality Score
The criticality score for this vulnerability is 7 out of 10. While not the highest severity rating, it indicates a high level of risk that demands immediate attention and action to mitigate potential damage.
Threat Type
The threat type associated with this vulnerability is classified as a vulnerability. It highlights an inherent weakness in the software that attackers can exploit if not properly addressed.
Recommendations for Users
