Server-side Request Forgery (SSRF)

Overview Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via the Host header when constructing response URLs for custom slash commands. An attacker can redirect responses to a server under their control by sending a specially crafted request with a spoofed Hos...

Faraday has a possible incomplete fix for GHSA-33mh-2634-fwr2 - protocol-relative URI objects still bypass host scoping

This bypasses the February 2026 fix for GHSA-33mh-2634-fwr2 and can redirect a request built from a fixed-base Faraday::Connection to ...
