Doc Text:
A flaw was found in Spring Framework. When Java scripting engine enabled template views (such as those using JRuby or Jython) are used in Spring MVC and Spring WebFlux applications, a remote attacker can exploit this to disclose sensitive content from files located outside the intended script template view directories. This information disclosure can expose confidential data.

Description OSIDB Bzimport 2026-03-20 00:02:44 UTC
Use of Java scripting engine enabled (e.g. JRuby, Jython) template views in Spring MVC and Spring WebFlux applications can result in disclosure of content from files outside the configured locations for script template views. This issue affects Spring Framework: from 7.0.0 through 7.0.5, from 6.2.0 through 6.2.16, from 6.1.0 through 6.1.25, from 5.3.0 through 5.3.46.
