Use of XsltView in a Spring MVC application can result in SSRF and RCE attack if the application has an "/**" mapping that results in view rendering, and where the view name is not explicitly specified. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49 Spring Framework 5.2.25.RELEASE and earlier
Casky was already ahead
This CVE exploits attack patterns that Casky's 351matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.
CVE-2026-47884 is a critical vulnerability affecting multiple versions of Spring Framework (5.2 through 7.0.8) that exploits insecure view resolution in Spring MVC applications. When an application uses XsltView with a catch-all "/**" URL mapping and fails to explicitly specify the view name, attackers can manipulate view parameters to trigger Server-Side Request Forgery (SSRF) and Remote Code Execution (RCE). This vulnerability has a CVSS score of 9.8 and impacts any organization running vulnerable Spring Framework versions in production, particularly those with permissive URL mappings and dynamic view resolution. The risk is severe because it requires minimal authentication and can lead to complete system compromise.
Casky's 351 mapped security skills leverage Claude AI's extended reasoning to detect exploitation patterns across MITRE ATT&CK techniques TA0001 (Initial Access) and TA0007 (Discovery). Practitioners using Casky would identify suspicious activity such as: unexpected XSLT template injection attempts in HTTP parameters, outbound connections from application servers to internal resources (SSRF indicators), unusual view name manipulation in Spring request handlers, and command execution traces following XsltView processing. The platform's skill mapping would flag request patterns that probe for implicit view rendering, detect attempts to load external XML/XSLT resources, and correlate reconnaissance activity with exploitation attempts—allowing security teams to distinguish between legitimate Spring MVC traffic and attack chains targeting this specific vulnerability.
