This link is maintained to preserve external references.\n\n## Original Description\nAllocation of Resources Without Limits or Throttling vulnerability in benoitc hackney allows Flooding. hackney_h3:await_response_loop/6 accumulates the HTTP/3 response body in memory without any size cap. The after Timeout clause is a per-message inactivity timer that resets on every received chunk, housekeeping message, or settings frame — it is not a wall-clock deadline. A malicious HTTP/3 server that emits one small chunk every Timeout - 1 ms with Fin = false and never sends a final frame keeps the loop alive indefinitely while the accumulation buffer grows linearly without bound, eventually exhausting the BEAM process heap and causing an out-of-memory condition.\n\nThis issue affects hackney: from 2.0.0 before 4.0.1.","public_affected_ranges":[">= 2.0.0, < 4.0.1"]}],"null_published_at":"2026-11-05T19:10:21.457Z","source_updated_at":"2026-06-30T17:15:57.000Z","source_disclosed_at":"2026-05-26T13:30:46.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-05T11:39:31.286Z"}],"next_cursor":null,"snapshot_revision":"42594"}
