Title
openEQUELLA before 2026.1.0 Remote Code Execution via FreeMarker Template Injection
Summary
openEQUELLA versions before 2026.1.0 contain a remote code execution vulnerability in FreeMarker template compilation due to an unsandboxed TemplateClassResolver configuration. Authenticated attackers can inject malicious template expressions through collection summaries, dashboard portlets, or MIME templates to instantiate dangerous classes like freemarker.template.utility.Execute and invoke Runtime.exec for arbitrary command execution.
CWE
  • CWE-1336 - Improper Neutralization of Special Elements Used in a Template Engine
