Bandit resizes its HPACK encoder table to whatever size the client advertises, up to 2^32-1 bytes, and indexes response headers into it. Because responses carry distinct values such as date or content-length, nothing is evicted and the table grows with every response for the life of the connection, while each lookup scans it linearly.\nThe SETTINGS handling in Bandit.HTTP2.Connection (lib/bandit/http2/connection.ex) passes remote_settings.header_table_size to HPAX.resize/2 with no server-side cap, and encode_headers encodes every response header as :store. Serving N responses on one connection therefore costs O(N\u00b2) CPU in the connection process.\nThis issue affects bandit: from 0.3.6 before 1.14.0.\nhttps://www.cve.org/CVERecord?id=CVE-2026-110499https://github.com/mtrudel/bandit/security/advisories/GHSA-47x4-3fxf-82frhttps://cna.erlef.org/cves/CVE-2026-110499.htmlhttps://osv.dev/vulnerability/EEF-CVE-2026-110499https://github.com/mtrudel/bandit/commit/0e68313fab9d204257ebad5c447e4cd9cea8e0eahttps://github.com/mtrudel/bandit/commit/220b9dfd27f9a21305be2afc75cbe585ddc24e7a#mtrudel
