CVE-2026-49753

Summary of the vulnerability : CVE-2026-49753 affects the Elixir Mint HTTP/1 client. The root cause is a lenient Content-Length parser in Mint.HTTP1.Parse.content_length_header/1, which accepts a leading + sign (e.g., +0, +123) despite RFC 7230 requiring unsigned digits only. When the same Mint c...
