I'd like to announce a new vulnerability chain we found that starts with an SVG parser bug. It affects multiple products and can lead to RCE.

I created https://t.co/3Tk4B6amtx to share more about the chain, which I'm calling "VectorFreed" for now.

I started looking into this early this month and have since confirmed command execution in several products that process SVGs. The root issue is CVE-2026-96889, with fixes in librsvg 2.63.2 and the 2.62.4 backport.

The repo has an early overview and references for now. I'll share the technical write-up in the coming weeks.

@mastomii If the app is using multiple workers/replicas probably, here since I used just a simple process it ends up crashing inevitably

We recently found a new RCE chain affecting the Node.js ImageResponse implementation in Next.js.

Vercel has published CVE-2026-94545. Next.js versions from 16.2.0 through 16.3.5 are affected. Upgrade to Next.js 16.3.6.

I'll share more details soon, once the remaining upstream advisories are out!

@kolovskydev Different rasterizers. Edge uses Resvg/WASM, while the Node path uses a different lib

After heist, we are still free

[s1r1us @S1r1u5_]

i wouldn’t be surprised if other incredible researchers soon find vulnerabilities with similar impact.

[sy.br1d @rafabd1_]

@S1r1u5_ who knows

when the AI provider does something similar: Look what did we do🤤🤤🤤🤤🤤
when some elite guys do it: 🤬🤬🤬🤬 youre being unprofessional🫪🫪🫪 stop 🤬🤬🤬🤬 youre violating my ego😭😭😭😭😭

We are not stopping at OpenAI.

Today we’re publishing HEIF Heist, a months-long investigation by our security research team into vulnerabilities in libheif.

The research uncovered attack paths affecting OpenAI, Slack, Meta, GitHub Enterprise, Rails, Next.js, ImageMagick and others.
