CVE-2026-59249

The CVE concerns the Elixir Mint library (mint) and its HTTP/1.1 decoding path. Specifically, Mint.HTTP1.decode_body/5 parses chunk-size lines using Integer.parse(data, 16), which accepts a leading + or - despite RFC 7230 requiring unsigned hex digits. This leads to a mismatch with RFC-strict int...
