### Security

• CVE-2025-61780 Improper handling of headers in

Rack::Sendfile

may allow proxy bypass.

• CVE-2025-61919 Unbounded read in

Rack::Request

form parsing can lead to memory exhaustion.

• CVE-2026-25500 XSS injection via malicious filename in

Rack::Directory

.

• CVE-2026-22860 Directory traversal via root prefix bypass in

Rack::Directory

.

### SPEC Changes

• Define

rack.response_finished

callback arguments more strictly. (#2365, `@​skipkayhil`)

### Added

• Add

Rack::Files#assign_headers

to allow overriding how the configured file headers are set. (#2377, `@​codergeek121`)

• Add support for

rack.response_finished

to

Rack::TempfileReaper

. (#2363, `@​skipkayhil`)

• Add support for streaming bodies when using

Rack::Events

. (#2375, `@​unflxw`)

• Add

deflaters

option to

Rack::Deflater

to enable custom compression algorithms like zstd. (#2168, `@​alexanderadam`)

• Add

Rack::Request#prefetch?

for identifying requests with

Sec-Purpose: prefetch

header set. (#2405, `@​glaszig`)

• Add

rack.request.trusted_proxy

environment key to indicate whether the request is coming from a trusted proxy.

### Changed

• Raise before exceeding a part limit, not after. (#2362, `@​matthew-puku`)

• Rack::Deflater now uses a fixed GZip mtime value. (#2372, `@​bensheldon`)

• Multipart parser drops support for RFC 2231

filename*

parameter (prohibited by RFC 7578) and now properly handles UTF-8 encoded filenames via percent-encoding and direct UTF-8 bytes. (#2398, `@​wtn`)

• The query parser now raises

Rack::QueryParser::IncompatibleEncodingError

if we try to parse params that are not ASCII compatible. (#2416, `@​bquorning`)

### Fixed

• Multipart parser: limit MIME header size check to the unread buffer region to avoid false

multipart mime part header too large

errors when previously read data accumulates in the scan buffer. (#2392, `@​alpaca-tc`, `@​willnet`, `@​krororo`)

• Fix

Rack::MockResponse#body

when the body is a Proc. (#2420, #2423, `@​tavianator`, [`@​ioquatix`])
