Title
Excon: redact additional sensitive/risky headers when following redirects
Summary
Excon is usable, fast, simple HTTP 1.1 for Ruby. Prior to 1.5.0, Excon's RedirectFollower middleware failed to strip additional sensitive headers when following redirects and did not provide a custom list of headers to strip. This could cause inadvertent leakage of sensitive data when the initial request includes header information that is not intended for the new target. This issue is fixed in version 1.5.0.

Title
In RubyGem excon, interrupted Persistent Connections May Leak Response Data
Summary
In RubyGem excon before 0.71.0, there was a race condition around persistent connections, where a connection which is interrupted (such as by a timeout) would leave data on the socket. Subsequent requests would then read this data, returning content from the previous response. The race condition window appears to be short, and it would be difficult to purposefully exploit this.

VAR-201912-1836
Vulnerability from variot - Updated: 2023-12-18 12:17In RubyGem excon before 0.71.0, there was a race condition around persistent connections, where a connection which is interrupted (such as by a timeout) would leave data on the socket. Subsequent requests would then read this data, returning content from the previous response. The race condition window appears to be short, and it would be difficult to purposefully exploit this. RubyGem excon Contains an input validation vulnerability.Information may be obtained. RubyGem excon is an HTTP server for Ruby applications.
There are security vulnerabilities in RubyGem excon versions prior to 0.71.0. An attacker could use this vulnerability to leak information
