      <title>GHSA-j4pr-3wm6-xx2r — URI Credential Leakage Bypass over CVE-2025-27221</title>
      <link>https://db.gcve.eu/vuln/ghsa-j4pr-3wm6-xx2r</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; RubyGems: uri&lt;/p&gt;
&lt;p&gt;### Impact&lt;/p&gt;
&lt;p&gt;In affected URI version, a bypass exists for the fix to CVE-2025-27221 that can expose user credentials.&lt;/p&gt;
&lt;p&gt;When using the `+` operator to combine URIs, sensitive information like passwords from the original URI can be leaked, violating RFC3986 and making applications vulnerable to credential exposure.&lt;/p&gt;
&lt;p&gt;The vulnerability affects the `uri` gem bundled with the following Ruby series:&lt;/p&gt;
&lt;p&gt;* 0.12.4 and earlier (bundled in Ruby 3.2 series)
* 0.13.2 and earlier (bundled in Ruby 3.3 series)
* 1.0.3 and earlier (bundled in Ruby 3.4 series)&lt;/p&gt;
&lt;p&gt;### Patches&lt;/p&gt;
&lt;p&gt;Upgrade to 0.12.5, 0.13.3 or 1.0.4&lt;/p&gt;
&lt;p&gt;### References&lt;/p&gt;
