Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-11-29 23:38:55 UTC

Sinatra is a domain-specific language for creating web applications in Ruby. An issue was discovered in Sinatra 2.0 before 2.2.3 and 3.0 before 3.0.4. An application is vulnerable to a reflected file download (RFD) attack that sets the Content-Disposition header of a response when the filename is derived from user-supplied input. Version 2.2.3 and 3.0.4 contain patches for this issue.

Please bump to 2.2.3 and 3.0.4.

Please stabilize when ready.

No GLSA, seems a bit esoteric to exploit and seemingly low impact anyway. Please cleanup.
