How to Fix CVE-2025-61594

To remediate this vulnerability, upgrade all affected Uri dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

uri fixed: 0.12.5 
Upgrade uri to 0.12.5
uri fixed: 0.13.3 
Upgrade uri to 0.13.3
uri fixed: 1.0.4 
Upgrade uri to 1.0.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for uri

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-61594, inspect your project dependencies for Uri:

inspect dependencies for uri

Analyze the terminal output to locate any version of Uri in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.12.5), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer, where the product stores, transfers, or shares a resource that contains sensitive information, but it does not properly remove that information before the product makes the resource available to unauthorized actors. In Uri, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact In affected URI version, a bypass exists for the fix to CVE-2025-27221 that can expose user credentials. 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. The vulnerability affects the `uri` gem bundled with the following Ruby series: * 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) ### Patches Upgrade to 0.12.5, 0.13.3 or 1.0.4 ### References * https://www.ruby-lang.org/en/news/2025/02/26/security-advisories/ * https://hackerone.com/reports/2957667
