    Update to version 3.1 (bsc#1274715).

    Security issues fixed:

    - CVE-2026-26961: rack: greedy multipart boundary parsing can lead to parser differentials and WAF bypass
      (bsc#1261398).
    - CVE-2026-26962: rack: improper unfolding of folded multipart headers can lead to downstream header
    injection and
      response splitting(bsc#1261471).
    - CVE-2026-34763: rack: unescaped regex interpolation of configured root path can lead to root directory
    disclosure
      (bsc#1261406).
    - CVE-2026-34230: rack: crafted `Accept-Encoding` headers can cause a denial of service (bsc#1261388).
    - CVE-2026-34785: rack: prefix matching logic can lead to the exposure of unintended files under the
    static root
      (bsc#1261417).
    - CVE-2026-34786: rack: URL-encoded path mismatch can lead to `header_rules` bypass (bsc#1261426).
    - CVE-2026-34826: rack: missing individual byte range limit checks when parsing HTTP `Range` headers can
    lead to
      excessive resource consumption and a denial of service (bsc#1261436).
    - CVE-2026-34829: rack: multipart parsing without `Content-Length` header can lead to unbounded chunked
    file uploads
      and a denial of service (bsc#1261447).
    - CVE-2026-34230: rack: quadratic complexity when processing of wildcard `Accept-Encoding` headers can
    lead to a denial
      of service (bsc#1261388).
    - CVE-2026-34830: rack: improper sanitization of the `X-Accel-Mapping` request header can lead to the
    exposure of
      unintended files via `X-Accel-Redirect` (bsc#1261458).
    - CVE-2026-34831: rack: `Content-Length` header and body byte size mismatch when creating error responses
    can lead to
      incorrect HTTP response framing (bsc#1261466).
