CVE-2025-27221 - userinfo leakage in URI#join, URI#merge and URI#+.

https://avd.aquasec.com/nvd/cve-2025-27221

There is a possibility for userinfo leakage by in the uri gem.
This vulnerability has been assigned the CVE identifier
CVE-2025-27221. We recommend upgrading the uri gem.

Details

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 could occur.

Please update URI gem to version 0.11.3, 0.12.4, 0.13.2, 1.0.3 or later.

Affected versions

uri gem versions < 0.11.3, 0.12.0 to 0.12.3, 0.13.0, 0.13.1 and
1.0.0 to 1.0.2.
