The V12 CLI starts a run on kestrel/streams and watches it complete with three findings, lists them, and shows the critical one.

Still alive in the wild, until it was found by V12.
Here's how EasyTimeline allowed arbitrary code execution (RCE) directly from wikitext.
AnyPwn: AnyDesk preauth 0click RCE (heap buffer overflow)
we will release PoC post disclosure and patch

Signal's Contact Discovery automatically sends your contact list information to an SGX enclave in the cloud.
V12 broke into that enclave and leaked the key, allowing the server host to decrypt everything.
Two separate critical bugs: arbitrary read and RCE.
Here's how. 🧵

Default configuration of WKWebView can cause downloaded files to instead be rendered on the host page.
This allows HTML injection, and sometimes even XSS, in countless iOS and WebKit apps.

A silent signature extraction in @Rabby_io, leading to a full wallet drain. 🧵
Arbitrum Nitro normally runs natively, but disputes rely on fraud proofs run in a WASM VM.
If these two environments don't fully agree, it can get ugly… like “L1 bridge funds ($2.8B) can be extracted” ugly.
Here's how V12 uncovered two independent mismatches, autonomously.

here's a mariadb RCE, what should we look at next?
we consistently find bugs human auditors miss
in this review for the Ethereum Foundation, we reported a unique High-severity bug. it stems from missing input validation
us and the human auditors found the same set of crits
Autopilot audits every change as soon as it lands. Autopilot starts runs for you. You can start a run on every push, for every PR, once a day, or once a week.

Tune the engine in your own words. A Steer is custom context on what a run should look for and what to leave alone. Tell V12 about past findings, runs, specs, or anything that you think matters.
Create a steer“We had our cryptography library audited by V12 alongside a human auditor. V12 caught every critical bug the human found and surfaced several issues the human missed. For a team our size, an independent review at this depth with both cryptographic and engineering insights was invaluable.”
“V12 has given us greater confidence throughout our Solana smart contract audit process. It consistently catches issues that are easy for humans to overlook, helping us identify potential vulnerabilities earlier and focus more of our time on validating complex attack scenarios. It’s become a valuable addition to our security workflow.”
“V12 found a critical soundness bug that had been lurking in our ZK code for over a year. Human expert auditors missed it. Since then, we’ve made V12 a central part of a security strategy. Better and cheaper than most human experts.”
“V12 has been great at spotting issues and helping us pipeline them into our production process. For Bulk, the biggest value is the loop: find risk, verify it, turn it into a ticket, fix, retest. Excited to see this loop get better every day!”
“We write a lot of complex cryptographic code, and security is always top of mind. Having a tool like V12 in our belt has been a huge lift for our security posture. We get detailed code review on complete repositories in hours, giving a boost in confidence for our engineers, researchers, and partners.”
“V12 is fantastic as another set of review eyes for your high velocity team. When fixing legacy code, it points out all the other ways it was already broken for you.”
