# A curl mountain movie

**[daniel.haxx.se](https://daily.dev/sources/danielhaxxse)** · 3 min read · 4 upvotes · 0 comments

## Summary

Daniel Stenberg, curl's creator, shares a visualization called 'the mountain' that tracks known vulnerabilities in curl across its entire history from 1998 to 2026. He created a script that renders the vulnerability chart for every month since curl's inception, producing a movie showing how the vulnerability count grew over time. Currently, curl 7.34.0 holds the record with 101 known vulnerabilities. The post also explores a notable drop in vulnerabilities around 2016 following a Cure53 security audit, though the exact cause remains unclear. The data is sourced from curl's vulnerability database and git history, with images assembled into a video using ffmpeg.
