SUSE CVE-2026-26962

Rack is a modular Ruby web server interface. From version 3.2.0 to before version 3.2.6, Rack::Multipart::Parser unfolds folded multipart part headers incorrectly. When a multipart header contains an obs-fold sequence, Rack preserves the embedded CRLF in parsed parameter values such as filename o...

CVE-2026-26962

A flaw was found in Rack, a modular Ruby web server interface. Rack::Multipart::Parser incorrectly processes folded multipart part headers, failing to remove embedded carriage return and line feed CRLF characters. This can lead to applications that reuse these parsed values in HTTP response heade...

Rack's improper unfolding of folded multipart headers preserves CRLF in parsed parameter values

Summary Rack::Multipart::Parser unfolds folded multipart part headers incorrectly. When a multipart header contains an obs-fold sequence, Rack preserves the embedded CRLF in parsed parameter values such as filename or name instead of removing the folded line break during unfolding. As a result,...
