Doc Text:	A flaw was found in the URI ruby gem package, where userinfo leakage can occur in the uri gem. The methods URI#join, URI#merge, and URI#+ retained userinfo, such as user:password, even after the host is replaced. When generating a URL to a malicious host from a URL containing secret userinfo using these methods, and having someone access that URL, an unintended userinfo leak can occur.	Story Points:	---

Description OSIDB Bzimport 2025-03-04 00:01:11 UTC

In the URI gem before 1.0.3 for Ruby, the URI handling methods (URI.join, URI#merge, URI#+) have an inadvertent leakage of authentication credentials because userinfo is retained even after changing the host.
