What is CVE-2026-53510?

The Savon Ruby SOAP client, specifically from versions 0.9.8 to 2.17.1, is vulnerable to a remote code execution flaw due to the interpolation of attacker-controlled WSDL operation names into the Ruby source code via module_eval. This vulnerability allows a malicious actor to execute arbitrary Ruby code within the application's process. The issue has been addressed in version 2.17.2, and users are strongly advised to upgrade to this version to mitigate the risk of exploitation.
