MongoBleed (CVE-2025-14847) is a globally exploited MongoDB Server vulnerability allowing remote memory leak without authentication, affecting numerous countries including China, the US, Germany, Hong Kong, Singapore, India, Russia, France, Vietnam, and Indonesia. The issue has been added to CISA's KEV catalog due to active exploitation. All federal civilian executive branch agencies in the US are advised to remediate by January 19. Prompt action is crucial to mitigate this global cybersecurity crisis.
MongoBleed is a critical vulnerability in MongoDB Server that allows attackers to remotely leak sensitive process memory. The vulnerability (CVE-2025-14847) can be exploited without authentication, affecting both internet-exposed and internally accessible databases. The impact of the vulnerability is global, with affected regions spanning across China, the US, Germany, Hong Kong, Singapore, India, Russia, France, Vietnam, and Indonesia. The vulnerability has been included in the U.S. Cybersecurity and Infrastructure Security Agency (CISA) Known Exploited Vulnerabilities catalog due to active global exploitation. Organizations relying on MongoDB Server are advised to address the vulnerability promptly, with a recommended remediation deadline of January 19 for US federal civilian executive branch agencies.
MongoBleed, a critical vulnerability in MongoDB Server, has left numerous organizations and individuals worldwide facing significant cybersecurity challenges. This highly exploited flaw, officially designated as CVE-2025-14847, allows attackers to remotely leak sensitive process memory from unpatched MongoDB servers using zlib compression, without authentication. The severity of this issue lies in its potential for widespread exploitation, given that any internet-facing MongoDB instance with zlib compression enabled is vulnerable.
MongoDB Server is a popular open-source NoSQL database used by numerous organizations worldwide due to its flexibility and scalability features. It stores data as JSON-like documents (called BSON) instead of traditional SQL tables and rows. This format makes it well-suited for modern applications requiring high performance and flexible data models. However, the unique architecture of MongoDB Server has led to this critical vulnerability.
CVE-2025-14847 was disclosed shortly after Christmas 2025, which might have coincidentally become a "gift" for cybersecurity professionals dealing with vulnerabilities. The discovery highlights a misconfiguration issue at scale, as many large cloud and hosting providers host vulnerable systems in their environments. According to Resecurity, the concentration of exposed MongoDB instances on these platforms suggests an automated exploitation process enabled across multiple tenants.
The vulnerability's impact is far-reaching due to its ability to be exploited remotely without authentication, affecting both internet-exposed databases and internally accessible instances that can be reached through lateral movement. The leaked process memory from affected servers could potentially expose sensitive information or even serve as a gateway for further attacks.
Geographically, the affected regions span across China, the United States, Germany, Hong Kong, Singapore, India, Russia, France, Vietnam, and Indonesia, indicating a global distribution of the vulnerability rather than regional isolation. The severity of this issue is underscored by its inclusion in the U.S. Cybersecurity and Infrastructure Security Agency (CISA) Known Exploited Vulnerabilities catalog, alongside warnings from the Australian Signals Directorate about active global exploitation.
The disclosure of CVE-2025-14847 comes as a stark reminder to all organizations reliant on MongoDB Server to address this vulnerability promptly. The inclusion in the CISA KEV catalog based on evidence of active exploitation signifies that the flaw is being actively used by malicious actors worldwide. U.S. federal civilian executive branch agencies are advised to remediate CVE-2025-14847 by January 19, further highlighting the urgency of addressing this issue.
The cybersecurity landscape has recently been marked by numerous high-profile incidents and vulnerabilities. However, the scope and impact of MongoBleed surpass those of most recent threats due to its potential for widespread exploitation and the large number of systems affected worldwide.
