The Alt-Svc response header parser in src/hackney_altsvc.erl does not guarantee forward progress. When parse_token/2 receives a non-token, non-whitespace, non-comma byte (e.g. !, @, =, ;), it returns the input unchanged. skip_comma/1 also returns the buffer unchanged when the first byte is not a comma. parse_entries/2 then recurses with identical data, creating a tight infinite tail-recursive loop that pins a scheduler at 100% CPU. The calling process never returns.</p> <p>The entry point parse_and_cache/3 is called synchronously in the connection process on every HTTP response. A single-byte Alt-Svc: ! response header is sufficient to trigger the hang; the header is fully controlled by any HTTP origin the client connects to.</p> <p>This issue affects hackney: from 2.0.0-beta.1 before 4.0.1.</p> <p><strong>Affected:</strong> benoitc hackney</p> <p>Loop with Unreachable Exit Condition (&#39;Infinite Loop&#39;) vulnerability in benoitc hackney allows Excessive Allocation.
