Main Content
The Cybersecurity and Infrastructure Security Agency (CISA) has escalated its response to a critical security flaw in MongoDB by adding CVE-2025-14847 to its [Known Exploited Vulnerabilities (KEV) Catalog](https://www.cisa.gov/known-exploited-vulnerabilities-catalog). This move follows confirmed reports of active exploitation, underscoring the urgency for organizations to address the vulnerability immediately.
Key Points
- Vulnerability Identified: CVE-2025-14847 affects MongoDB and MongoDB Server, stemming from an improper handling of length parameter inconsistency.
- Active Exploitation: The vulnerability is being actively exploited by malicious cyber actors, posing significant risks to federal and enterprise networks.
- Federal Mandate: Under Binding Operational Directive (BOD) 22-01, Federal Civilian Executive Branch (FCEB) agencies are required to remediate this vulnerability by the specified due date.
- Broader Impact: While BOD 22-01 applies only to federal agencies, CISA strongly recommends that all organizations prioritize patching this vulnerability to reduce exposure to cyberattacks.

Technical Details
CVE-2025-14847 is classified as an improper handling of length parameter inconsistency vulnerability. This type of flaw can allow attackers to manipulate input parameters, leading to unauthorized access, data corruption, or remote code execution. MongoDB, a widely used NoSQL database, is particularly attractive to threat actors due to its prevalence in enterprise environments, including cloud-based deployments like MongoDB Atlas.
#### Affected Systems
- MongoDB Server (all versions vulnerable to CVE-2025-14847)
- MongoDB Atlas (if running affected versions)
- Custom deployments of MongoDB in enterprise environments

Attack Vector
Malicious cyber actors are exploiting CVE-2025-14847 to:
1. Gain unauthorized access to sensitive data stored in MongoDB databases.
2. Execute arbitrary code on vulnerable systems, potentially leading to full system compromise.
3. Disrupt operations by corrupting or deleting critical data.
The vulnerability is particularly dangerous because MongoDB is often used to store unstructured data for web and mobile applications, making it a prime target for data breaches.

Impact Assessment
The inclusion of CVE-2025-14847 in CISA’s KEV Catalog signals its high severity and active exploitation in the wild. Organizations that fail to remediate this vulnerability risk:
- Data breaches leading to exposure of sensitive information.
- Operational disruptions due to system compromises.
- Compliance violations for federal agencies and regulated industries.
- Reputational damage and financial losses stemming from successful attacks.

Mitigation Steps
CISA and MongoDB Inc. have outlined the following steps to mitigate the risks associated with CVE-2025-14847:
1. Apply Patches Immediately:
- Update MongoDB Server to the latest patched version provided by MongoDB Inc.
- For MongoDB Atlas users, ensure automatic updates are enabled or manually apply the latest security patches.
2. Follow CISA Guidelines:
- Federal agencies must adhere to the remediation deadline specified in BOD 22-01.
- Non-federal organizations should prioritize this vulnerability in their vulnerability management programs.
3. Monitor for Suspicious Activity:
- Deploy intrusion detection systems (IDS) and security information and event management (SIEM) tools to detect exploitation attempts.
- Review logs for unusual access patterns or unauthorized data modifications.
4. Implement Network Segmentation:
- Isolate MongoDB servers from public-facing networks to limit exposure.
- Restrict access to databases using firewalls, VPNs, and zero-trust policies.
5. Educate Staff:
- Train employees on recognizing phishing attempts and other social engineering tactics that may precede exploitation.

Conclusion
The addition of CVE-2025-14847 to CISA’s KEV Catalog serves as a critical reminder of the ongoing threats posed by unpatched vulnerabilities. Organizations must act swiftly to remediate this flaw, particularly given its active exploitation by malicious actors. While federal agencies are mandated to comply with BOD 22-01, all organizations are urged to prioritize this vulnerability to safeguard their systems and data.
