What is CVE-2025-52479?

The HTTP.jl and URIs.jl libraries developed by JuliaWeb are vulnerable to CRLF injection due to improper handling of user input in URI construction. Specifically, versions prior to HTTP.jl 1.10.17 and URIs.jl 1.6.0 allow the inclusion of carriage return (CR) and line feed (LF) characters in URIs, which can be exploited by attackers to inject arbitrary HTTP headers. Users are urged to upgrade to the latest versions to mitigate this vulnerability. For those unable to upgrade immediately, it is advised to manually validate any URIs before processing them to prevent potential exploits.

Affected Version(s)

HTTP.jl < 1.10.17
