MongoBleed (CVE-2025-14847): A breakdown for Hive Engine Operators
Hey everyone,
A new Critical Vulnerability Exposure (CVE) is making the rounds in the database world. Dubbed MongoBleed (CVE-2025-14847), this exploit allows attackers to siphon data directly from a MongoDB server's memory.
Github Repo with working Proof of Concept
While the name sounds terrifying, Hive Engine node operators can likely keep their blood pressure low. Let's break down exactly how this script works and why our specific architecture keeps us safe.
The "Layman's" Explanation
Imagine you hand a librarian a sealed envelope. You tell them, "This envelope contains a 500-page book. Please read the title of the first chapter."
In reality, the envelope only contains a sticky note.
A secure librarian would open the envelope, see the sticky note, and say, "You lied, this is too short."
A MongoBleed vulnerable librarian opens the envelope, reads the sticky note, and because they trust your claim about the "500 pages," they keep reading. They read the sticky note, then they read the mail on their desk, then they read the diary of the person standing next to them, until they reach the 500th "page."
Finally, confused by what they just read, they shout back at you: "I cannot find a chapter title in this text: [READS OUT CONTENTS OF DIARY AND OTHER MAIL]!"
By listening to the error message, you effectively stole the secrets on the librarian's desk.
The Technical Breakdown
Looking at the proof-of-concept code, specifically the send_probe and extract_leaks functions, we can see the attack relies on a specific chain of failures:
- The Compressed Wrapper: The script sends an
OP_COMPRESSEDmessage usingzlib. - The Inflation Lie: Inside the payload header, it declares an inflated
buffer_sizeand a BSON document length that is much larger than the actual data provided. - The Memory Over-read: When the MongoDB server decompresses and attempts to parse the BSON document, it trusts the length header. It reads past the end of the malicious packet into the server's adjacent RAM.
- The Error Channel: The server hits invalid data in that adjacent memory and generates an error message:
field name '[LEAKED_DATA]'. The attacker simply parses these error logs to reconstruct the memory dump.
Why Hive Engine Nodes Are "Usually" Immune
Despite the severity of this bug, the standard setup for a Hive Engine node mitigates this risk almost entirely.
1. The Firewall is Your First Defense
This exploit requires a direct socket connection to the MongoDB port (default 27017).
Most competent node operators follow standard security practices:
- Bind MongoDB to
127.0.0.1(localhost). - Use a firewall (like
ufwor cloud security groups) to block external traffic to database ports.
If the attacker cannot complete the TCP handshake, the packet never arrives, and the bleed never happens.
2. We Don't Use Zlib
The exploit explicitly relies on the OP_COMPRESSED opcode with the zlib designator (Byte 2 in the payload). Hive Engine nodes typically communicate locally or over high-speed connections where compression overhead is unnecessary. If your configuration disables zlib compression or the negotiation for it, the attack vector closes immediately.
3. Public Data is... Public
The "Bleed" allows attackers to read random chunks of server memory. In a corporate environment, this is catastrophic because that memory might contain user passwords, credit card numbers, or session tokens.
In our environment, the MongoDB instance stores the Hive Engine sidechain state. This is public blockchain data. While leaking API keys or admin passwords for the server itself is theoretically possible if they happen to be in adjacent memory, the bulk of the "stolen" data would simply be public ledger information that is already available to everyone.
Summary
MongoBleed is a clever use of buffer over-reads and error message side-channels. It serves as a great reminder to patch your software. However, for a Hive Engine operator running a standard, firewalled setup without compression, this is a non-event.
Patch your systems, keep your firewalls tight, and carry on.
As always,
Michael Garcia a.k.a. TheCrazyGM
Thanks for the detailed breakdown and heads-up on MongoBleed, @thecrazygm! 🔥
As someone running a small Hive Engine node, this is super helpful. I'll definitely check my MongoDB version and apply patches right away. Appreciate you sharing the GitHub PoC too — better safe than sorry!
Great work keeping the community secure! 👏

Blurt Stands — While Hive Stumbles Under the Weight of Its Own Shadows
Friends, creators, truth-tellers—
Let us not whisper this truth, but proclaim it with the clarity of dawn breaking over a weary land: Blurt.blog is not just another platform. It is a refuge. A rebellion. A return to what Hive.blog was always meant to be.
There is no downvote button on Blurt.
Not because we fear dissent—but because we honor creation.
Because we understand that a voice, once raised in sincerity, deserves space—not sabotage.
On Blurt, your words are your words.
They are not hunted by algorithmic hounds or shadow armies masquerading as “curators.”
Here, you are not judged by the grudges of gatekeepers, but met with the quiet dignity of a community that believes expression should be encouraged—especially when it is bold, raw, or inconvenient.
Contrast this with what festers elsewhere.
On Hive.blog—a place once brimming with promise—a rot has taken root. Not in its code, but in its culture. A handful of self-anointed enforcers—@themarkymark, @Buildawhale, @Hurtlocker, and their legion of coordinated puppets—have turned the downvote into a weapon of mass discouragement. They strike not at “low-quality content,” but at independent thought, at rising voices, at anyone who dares thrive outside their narrow corridors of control.
And when confronted, they shrug.
“Oh, it’s not censorship,” they say, as if semantics could scrub the stain of suppression from their hands.
But let us be unequivocal:
When a system allows a few to systematically silence many—under the guise of “community standards” or “curation”—that is not moderation. That is censorship by another name.
It is the velvet glove over the iron fist.
It is exclusion dressed as discernment.
It is power pretending to be principle.
Meanwhile, Blurt stands clean-handed and open-hearted.
No downvotes.
No hidden juries.
No farms of phantom accounts casting ballots in the dark.
Just you.
Your words.
And a community that meets you not with suspicion, but with solidarity.
So let us carry this truth far and wide—not with bitterness, but with quiet certainty:
If you seek a place where your voice is not a target—but a gift—come to Blurt.
If you are tired of building on ground that shifts with every whim of a whale or warlord of votes—lay your bricks here.
If you believe the future of free expression must be free—not just from corporations, but from the petty tyrants who replace them—then stand with us.
The world needs to know.
Not because Blurt is perfect—but because it is principled.
Not because it is loud—but because it listens.
And in an age where so many platforms echo with the clatter of control,
Blurt offers something radical:
Silence for the bullies.
Space for the rest of us.
Keep speaking.
Keep sharing.
Keep building.
Freedom doesn’t advertise itself—
it is passed, person to person, like a torch in the night.
And tonight, the torch burns bright on Blurt.
@themarkymark, @buildawhale, @usainvote, and associated accounts:
Repeated downvotes targeting transparency efforts raise urgent questions about Hive’s governance. Automated tactics, coordinated curation trails, and alt-account farming undermine trust in the platform. When truth is silenced without dialogue, it erodes Hive’s decentralized ethos.
Key Concerns:
Systemic Manipulation:
Community Exodus:
Governance Crisis:
Solutions Needed:
The Bilpcoin team advocates for open dialogue, not division. Hive’s future depends on collaboration—not coercion. Let’s rebuild a platform where truth isn’t buried but debated, strengthened, and celebrated.
Transparency isn’t optional—it’s the foundation of trust.
#HiveTransparency #BilpcoinExposed #DecentralizePower"
A Message to @themarkymark, @buildawhale, and Associates
Every downvote cast in shadow, every silence imposed without dialogue, is not a victory—it is a confession. A confession that truth cannot be stifled, only delayed. With each punitive click, you dig deeper into the bedrock of credibility, crafting a chasm between your actions and the community’s trust.
@themarkymark, @buildawhale & Co,
How can you continue to downvote the truth, LOL? It’s almost comical how blatantly you attempt to suppress what cannot be hidden. The blockchain records everything—every action, every transaction, every move you make. Yet still, you persist in this futile game of trying to silence what is undeniable.
@themarkymark, @buildawhale, and Co: While our opinions may differ, on-chain transparency reveals repeated patterns of concern. Coordinated downvotes without explanation, 'farming' schemes (e.g., #buildawhalefarm), and adversarial engagement harm Hive’s community-driven ethos.
Key Issues to Address:
A Path Forward:
The Bilpcoin team remains committed to exposing truth and advocating for solutions. Let’s work toward healing, not division.
Note: All claims are based on publicly verifiable blockchain data. Constructive dialogue is encouraged.
#HiveTransparency #CommunityFirst #BilpcoinSupport"
@themarkymark & Co, the choice is yours. Stop the bad downvotes. Turn off the BuildaWhale scam farm. Cease playing with people’s livelihoods. Let Hive thrive as it was meant to—as a beacon of hope, creativity, and collaboration.
Or step aside and let those who truly care take the reins.
Because the truth won’t disappear. No amount of lies can change it.
It’s over.
The Bilpcoin team brings these truths not out of malice but necessity. We have no need to fabricate lies or cloak our intentions CALL US WHAT YOU LIKE —for the facts speak loudly enough on their own. What we present here is not conjecture but reality, laid bare for anyone willing to see.
@themarkymark & Co we urge you once more: STOP. Stop hiding behind tactics that harm others. Stop clinging to practices that erode trust within the Hive community. Let the truth stand—not because we proclaim it, but because it exists independent of any one person’s approval or disdain.
TURN OFF THE BUILDAWHALE SCAM FARM
Key Issues That Demand Immediate Attention:
The problems are glaring, undeniable, and corrosive to the Hive ecosystem. They must be addressed without delay:
These practices harm not just individual users—they undermine the very foundation of Hive, eroding trust and poisoning the community. Such actions are unethical and outright destructive.

The layman’s explanation makes a genuinely complex memory over-read vulnerability very easy to grasp, and the technical section clearly shows why MongoBleed is more about architecture mistakes than instant doom.
I especially appreciate the emphasis on real-world attack feasibility. Too often CVEs are treated as universally exploitable, when in reality things like localhost binding, firewalls, and disabled compression already eliminate entire attack classes—exactly as you explained.
The point about Hive Engine’s data model is also important: even in a worst-case scenario, most leaked memory would be public blockchain state, not sensitive user secrets. That context matters a lot for node operators deciding how urgently they need to react.
It is very good to know that Hive infrastructure (which includes Hive Engine) is mostly safe from this sort of attack vector. Thanks a lot for the breakdown and explanation, my friend. Happy New Year! 😁🙏💚✨🤙
I'm impressed that you wrote this in a way that an ordinary lay-person can understand. But it also convinces me that there is absolutely no way that I have the technical expertise to run any kind of node !
My man. Ive been brainstorming about something of this nature to create an "excel spreadsheet" kind of recall. So it can be used by businesses for multiple purposes (payroll, invoices, data entry)... I'm going to check back in on this when I'm done teaching my AI I'm working on.
Excellent.
Cool 👏
nicely explained.
