In lib/mint/http1.ex, decode\\_status\\_line/4 stores the unconsumed data in conn.buffer when the status line is incomplete, and decode\\_body/5 does the same for an unterminated chunk-extension line. Both wait for a CRLF the server never has to send, and conn.buffer is prepended to every subsequent socket message. The :max\\_header\\_list\\_size budget is wired only into decode\\_headers/5 and decode\\_trailer\\_headers/4, so neither of these states is covered by it. A malicious server, or one reached through an attacker-controlled redirect or a fetched URL, streams bytes indefinitely until the BEAM node is killed by the operating system out-of-memory handler. The chunk-extension variant is reached after a valid status line and a complete, valid header section, so an intermediary inspecting only headers sees an ordinary 200 response.\n\nThis issue affects mint: from 0.1.0 before 1.10.0.","id":"EEF-CVE-2026-82728","modified":"2026-09-04T14:31:30.897958Z","published":"2026-09-04T14:31:30.059Z","references":[{"type":"ADVISORY","url":"https://github.com/elixir-mint/mint/security/advisories/GHSA-g83f-2j6r-q6m4"},{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-82728.html"},{"type":"FIX","url":"https://github.com/elixir-mint/mint/commit/19be5558b6a317e271c78666498dd78b151e490a"},{"type":"PACKAGE","url":"https://hex.pm/packages/mint"}],"related":[],"schema_version":"1.7.3","severity":[{"score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","type":"CVSS_V4"}],"summary":"Unbounded HTTP/1 status-line and chunk-extension buffering in Mint causes memory-exhaustion DoS","upstream":[]}
