Description

Http4s is a Scala interface for HTTP services. Starting with version 0.1.0 and prior to versions 0.21.34, 0.22.15, 0.23.17, and 1.0.0-M38, the `User-Agent` and `Server` header parsers are susceptible to a fatal error on certain inputs. In http4s, modeled headers are lazily parsed, so this only applies to services that explicitly request these typed headers. Fixes are released in 0.21.34, 0.22.15, 0.23.17, and 1.0.0-M38. As a workaround, use the weakly typed header interface.

Affected configurations

• typelevel http4s (>= 0.1.0 < 0.21.34) • typelevel http4s (>= 0.22.0 < 0.22.15) • typelevel http4s (>= 0.23.0 < 0.23.17) • typelevel http4s 1.0.0
