We recently wrote about 21 FFmpeg zero-days we found earlier this year. Read the blog post about the findings and about how our security agent works in the comments.
🔥 AI just found 21 zero-days in FFmpeg.
That’s the video library bundled inside many apps, tools, containers, and devices. Some bugs sat untouched for 15–20 years.
Google Chrome also dropped PATCHES for a record 429 vulnerabilities this week.

We helped FFmpeg find and fix 21 security vulnerabilities.
In a 1.5M-line codebase, we spent just $1K in API costs. Some of these bugs had been hiding for decades.
We also developed a PoC demonstrating an RCE primitive when FFmpeg processes RTSP streams.
Full write-up: depthfirst.com/research/21-ze…
AI agents are enabling every team to build useful software. This is incredibly exciting, but it also means the attack surface is changing. We recently learned that our adversaries are already using frontier models to create malware and exploit vulnerabilities.
To address this, today we’re launching the depthfirst Dependency Firewall to find and block malware in supply chain dependencies before they’re installed.
It uses the same engine that discovered NGINX Rift, now optimized to detect malware in open-source packages.
We want companies to move faster with AI, without compromising security.
Above all, @depthfirstlabs is a mission driven organization. This is another step towards achieving our mission of securing the world's software, an increasingly urgent need as artificial intelligence accelerates how software is built, deployed and attacked.
@sebuzdugan@qasimmith Agree with you @sebuzdugan - that's why depthfirst verifies exploitability conditions to surface real findings and minimize false positives
Today we're launching the Open Defense Initiative: up to $5 million in @depthfirstlabs credits for critical open source projects to find and fix real, exploitable vulnerabilities.
The timing matters: frontier models can autonomously discover and exploit vulnerabilities in
Thanks @Forbes for the coverage. We want to give all defenders access to frontier-level security, today.
We're offering $5m in credits to maintainers of critical OSS. Apply here: opendefense.dev
Still "Lab", but working fully remotely without any hardcoded offsets, bypassing ASLR on standard Ubuntu + Nginx deployment via an LFI primitive. There's still lots of room for improvement but I'm already out of tea and who cares? Just patch.
.@depthfirstlabs found NGINX Rift. We're giving $5m in credits to critical OSS projects, apply below.
Regarding ASLR, please prioritize patching. ASLR makes the exploit harder, but still feasible.
🚨 UPDATE: 19 MILLION exposed NGINX instances hit by the 18-year-old NGINX RCE found by AI.
Top exposure by country:
- United States: 5,340,011
- China: 2,540,008
- Germany: 1,871,780
Note on ASLR as added security: not all of these instances will have ASLR disabled, but every
Because regex-triggered vulnerabilities depend on the specific regex input, they are especially difficult for static analyzers (and humans) to find. This is impressive.
NGINX rift: We autonomously discovered this 18 yr old heap overflow (CVE-2026-42945) in @nginx impacting version 0.6.27 to 1.30.0. If you use rewrite and set directive, you maybe impacted! Please update your NGINX or change the config to mitigate it. Read more at
Using the same system, we found NGINX RCE, Linux LPE, Chrome RCE, FFmpeg RCE and a lot of other critical Vulnerabilities, feel free to try it out! We are trying our best to help secure OSS!

depthfirst autonomously discovered, verified, and generated a patch for NGINX rift, an 18 year old heap overflow (CVSS 9.2). It leads to an RCE and is affecting most of the global web traffic.

@nginx powers a large portion of global web traffic, and is used by major companies to run and secure their web services. This code had been there for 18 years and run countless times before we found the vulnerability.
@depthfirstlabs found a critical vulnerability in @nginx leading to RCE (CVE-2026-42945, CVSS 9.2). We recommend patching to 1.30.1 or 1.31.0 as as possible.
Securing the world software is depthfirst mission and NGINX is one of the most widely deployed web server in the world
