Bumps bandit from 1.12.5 to 1.13.1.

Changelog

Sourced from bandit's changelog.

1.13.1 (15 Oct 2026)

Reverts

• Revert the stale conn check added in 1.13.0 (#668), since a number of valid code paths in Phoenix depend on stale conns (notably, Plug.Parsers errors rendered by Phoenix.Endpoint.RenderErrors). See elixir-plug/plug#1331

1.13.0 (15 Oct 2026)

Enhancements

• Add a compress_chunked option to compress chunked responses with gzip and zstd (#707, thanks @​iStefo!)
• Clarify inet6 option behaviour on dual-stack platforms (#709, #700, thanks @​adelton!)
• Unroll WebSocket masking over 32-byte blocks (#674, thanks @​mpettibone!)
• Drain HTTP/2 pending sends without repeated List.delete/2 (#673, thanks @​mpettibone!)
• Short-circuit header token lookup on the first match (#699, thanks @​claytongentry!)
• Scope the workflow tokens to what each job actually uses (#702, thanks @​Totara-thib!)
• Add a Plumber check and score badge (#712, thanks @​Totara-thib!)
• Fix recent releases changelog headings in docs (#672, thanks @​dinokovac-river!)

Changes

• Require Thousand Island 1.6, and use the peername it now captures when it accepts a connection (#718)
• Require hpax 1.1 and drop the nil field value workaround (#706, thanks @​acrogenesis!)
• Report conn.port as an integer for CONNECT requests, as Plug.Conn requires
• Close idle connections which send no bytes silently instead of answering 408 (#689, thanks @​tomciopp!)
• RFC Conformance: Enforce Host requirements for HTTP/1.1 targets (#679, thanks @​mpettibone!)
• RFC Conformance: Complete HTTP/2 field validation (#680, thanks @​mpettibone!)
• RFC Conformance: Validate HTTP/2 content length on initial END_STREAM (#681, thanks @​mpettibone!)
• RFC Conformance: Enforce HTTP/2 trailer field section requirements (#682, thanks @​mpettibone!)
• RFC Conformance: Validate request transfer coding before Plug dispatch (#683, thanks @​mpettibone!)
• RFC Conformance: Fix HTTP/1.0 streaming response framing (#684, thanks @​mpettibone!)
• RFC Conformance: Accept empty non-final WebSocket continuation frames (#685, thanks @​mpettibone!)
• RFC Conformance: Validate WebSocket client keys (#686, thanks @​mpettibone!)

Fixes

• Validate the authority of HTTP/1 absolute-form and authority-form request targets against the same grammar as the Host header (GHSA-v53v-9hvg-37jf, thanks @​euriconicacio!)
• Bound HTTP/2 sends blocked on a send window by progress, so that a trickle of window updates can no longer keep a stream pinned indefinitely (GHSA-69m6-wcv4-rwcf, thanks @​tomciopp!)
• Reject control bytes in HTTP/1 request targets (#713, #711, thanks @​PJUllrich!)
• Fix crash when a client resets an HTTP/1 connection before Bandit reads its peer address (#718, #717, thanks @​mhsdef!)
• Drain all queued HTTP/2 DATA frames of an unread body once a response has been sent (#710, #697, thanks @​jamilbk!)
• Preserve independent error responses on HTTP/1 keep-alive and pipelined requests, and frame empty 4xx/5xx error responses with Content-Length: 0 (#705, thanks @​jeregrine!)
• Close instead of draining when a plug never honors Expect: 100-continue (#695, thanks @​tomciopp!)
• Fix chunked read_body(length: 0) falsely completing the body (#691, thanks @​tomciopp!)
• Observe RST_STREAM while blocked on the stream send window (#688, thanks @​tomciopp!)
