TL;DR
A public GitHub repository named 'mongobleed' hosts a Python file whose latest commit labels it as a CVE-2025-14847 "MongoDB Memory Leak Exploit." The repository is public and shows a small number of forks and stars, but the source metadata does not include technical details, affected versions, or proof of exploitability.
What happened
A repository called 'mongobleed' authored by user joe-desimone contains a file named mongobleed.py. The most recent commit message on the repository describes the file as "CVE-2025-14847 MongoDB Memory Leak Exploit." The project is public on GitHub, shows 43 stars and 5 forks in the visible metadata, and the mongobleed.py file is reported as approximately 4.26 KB with 129 lines. The repository listing and file metadata are available at the provided GitHub URL. The publicly shown information is limited to repository and file metadata; the visible excerpt does not include a full description of the vulnerability, affected MongoDB versions, exploit mechanics, or any vendor advisory. Where specific technical or impact details are absent in the repository metadata, those points cannot be confirmed from the source.
Why it matters
- Public posting of code labeled as an exploit can increase risk of misuse if it is functional or easily adapted by others.
- Security teams need awareness of potential proof-of-concept code so they can verify whether their deployments are affected and apply mitigations.
- Tracking references to a CVE identifier is important for correlating code samples with official vendor advisories and patch timelines.
- Even limited metadata can prompt investigations by defenders and incident responders to determine exposure and detection needs.

Quick glossary
- CVE: Common Vulnerabilities and Exposures — a standardized identifier for publicly known cybersecurity vulnerabilities.
- Proof of Concept (PoC): Code or a demonstration showing how a vulnerability might be exploited; presence of a PoC does not by itself confirm broad exploitability.
- Memory leak: A software defect where a program incorrectly retains memory it no longer needs, which can degrade performance or cause crashes.
- GitHub repository: A hosted project workspace on GitHub where code, commits, issues, and other project metadata are stored and shared.
Reader FAQ
Does the repository contain exploit code for CVE-2025-14847?
The latest commit message labels mongobleed.py as a "MongoDB Memory Leak Exploit" tied to CVE-2025-14847, but the repository metadata alone does not confirm the presence, functionality, or completeness of exploit code.
Are specific MongoDB versions affected?
