http4k before 6.62.0.0-ee Path Traversal via ThymeleafTemplates Template Resolution

Published Nov 2, 2026 CVSS 4.0 · 8.2 High EPSS < 1% KEV · Not listed
Description
http4k before 6.62.0.0-ee contains a path traversal vulnerability in ThymeleafTemplates Caching and HotReload that allows unauthenticated attackers to read files outside baseTemplateDir by supplying ../ segments in ViewModel.template() values. Attackers can influence request-driven template selection so Thymeleaf's FileTemplateResolver resolves escaped paths without containment checks, disclosing any file readable by the server process.
