**Name of the Vulnerable Software and Affected Versions** jruby-openssl gem versions prior to 0.6 **Description** A security issue was found in the handling of SSL certificate validation, where failed verification did not properly alert the application, making it vulnerable to attacks. This could allow attackers to make a client believe a connection to a rogue SSL server is legitimate or to penetrate client-validated SSL server applications using a dummy certificate. **Recommendations** For versions prior to 0.6, update the jruby-openssl gem to version 0.6 or later to resolve the issue. As a temporary workaround, consider disabling SSL connections until the update is applied. Restrict access to sensitive applications using the jruby-openssl gem to minimize the risk of exploitation.
