Daniel Stenberg
Daniel Stenberg is a Swedish open-source software developer best known for creating and maintaining the curl and libcurl network transfer projects. He has deep technical expertise in network protocols, HTTP, and data transfer, and is active in the open-source community with a focus on network security and software quality. The curl tool he developed is widely used in operating systems, embedded devices, and various software projects, forming a key component of internet infrastructure.
Timeline (last 90 days)
curl is an open-source project initiated by Daniel Stenberg in 1996, and its name means Client URL, relying on the libcurl library to make network requests.
The curl project shut down its bug bounty program in January 2026 because it had received seven reports in the previous week and not one described a real vulnerability, and lead developer Daniel Stenberg said the move was aimed at eliminating the incentive for "junk and insufficiently researched reports".
Stenberg described the total number of curl vulnerabilities found by AISLE audits over roughly the past year as "no fewer than 35 published curl vulnerabilities and CVE IDs".
The curl project ruled out rewriting curl (neither switching to another language nor switching away from C), instead using transport identifiers in place of internal handle pointers and adding tests and analyzers.
Daniel Stenberg, maintainer of the curl project, has bluntly stated that AI-generated false security reports are wasting his team's valuable time.
curl has long been primarily maintained by a single core maintainer, Daniel Stenberg, presenting a critical personnel risk known as a bus factor of 1.
curl is a command-line tool and library for transferring data over various network protocols, created in 1998 by Swedish developer Daniel Stenberg.
The curl project operates a bug bounty program through the HackerOne platform, and Stenberg has referred to the behavior of submitting AI-generated false vulnerability reports as "AI security washing".
