CVE-2026-53510 Details
Description
Savon is a Ruby SOAP client. From 0.9.8 until 2.17.2, Savon::Model .all_operations interpolates attacker-controlled WSDL operation names into Ruby source passed to module_eval, allowing Ruby code execution in the application process. This issue is fixed in version 2.17.2.
A code injection vulnerability has been identified in the Savon Ruby gem, specifically in versions 0.9.8 prior to 2.17.2. The issue arises in the Savon::Model class, where the .all_operations method interpolates WSDL operation names into Ruby code executed via module_eval. This behavior allows an attacker to inject and execute arbitrary Ruby code in the application process, provided they can control the operation names in the WSDL. The vulnerability is present only when using the .all_operations method with untrusted WSDL documents. The issue has been patched in Savon version 2.17.2.
Users are advised to upgrade to Savon version 2.17.2 or later. For those using version 2.17.0, the Faraday transport option has been reintroduced to handle cookies correctly.
