CVSS 3.1
5.3 mediumCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:NCVE-2025-27221
Medium (5.3) in ruby-lang uri. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in uri 0.11.3, 0.12.4, 0.13.2.
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.
